Erik, i am very impressed how deep you are going in detail and support us reloaders with all your experience. Very very worthful and not to find elsewhere. Thank you at this point
Well done Erik. As a Induction annealer manufacturer ourselves we love the independent testing between the two technologies. We await the rest of your testing and results!!!
The numbers (161 vs 155) from clean new brass vs clean neck turned is just under 4% difference. Although it’s nice to be “spot on”, is that enough difference to make a meaningful difference in the hardness, if any, resulting from the annealing from the induction annealing?
Hi Richard. I can't speak for amp. We manufacture our own machines/brand. But yes there is time differences between dirty and clean cut brass. On ours depending on the brass manufacturer and what calibre brass anything from 0.1 - 0.3 sec difference. Dirty = longer time = more heat to anneal Clean & cut = less time = less heat. For consistency it is best to use correct settings and it is easy to achieve those settings. For hunting and prs/nrl shoots you probely won't notice, fclass and elrs maybe that is what you need on that level. Cheers
I love the attention to detail. This is how we transition away from doing things just because we heard it was good, towards doing things because it gets results. I got a rifle with a proof barrel that still shoots better than me, but taking the time to explore hand loading has improved the accuracy notably
Thank you for your efforts to share your knowledge & test results. A note! I would suggest you acquire a Webster hardness tester! The AMP machine has a test to determine the setting, but as with all other reloading equipment, you need a way to test an verify that the machine is working correctly! For the propane annealing, you really need to test to verify for every batch, since this method is less reliable. If you guesstimate the intensity of the flame, your don't have a 100% repeatable process. To tweak the propane to hit your target for hardness reliable for different brand of brass, your only option is to test hardness. Also you might have other needs than the "auto" functionality of the AMP allows. If factory brass is hardness 13 on the W-B75b, then you need a way to confirm that your annealing results are 13. Or if your needs for neck tension are different than hardness of 13 allows, then you need to be able to test. A test series of a verified increments in hardness, allows you to adjust to your needs & verify results. Trial an error approach is possible, but probably more time consuming & costly, compared to test based on verified hardness after annealing. If you don't really know why what you do works, then it might be really difficult to work out what might be wrong, if it stops working for you. The main models for Brass are: W-B75 & W-B92 : www.amazon.com/dp/B07T3ZH89R/?coliid=I2QVPCSR156ABL&colid=2X111SDZ9N710&psc=1&ref_=lv_ov_lig_dp_it & The "W-B75" come in 3 other versions: W-B75b, W-BB75 & W-BB75b . W-B75b test range is 63-105HRF. W-BB75b test range is 18-100HRE. Both for >6mm inner tube diameter.
Great stuff Mr.Cortina as usual. Ive been looking at the annealeez setup since its closer to my price range your flame annealer isnt super spendy either compared to the Amp system. Thanks for the video!
As always, well done Erik! You always teach me something every time I watch your videos. I am not a bench rest shooter; however I demand that my hunting loads be extremely accurate. I am on the fence about annealing and I am pretty sure I am going to take the leap and buy an annealer and get started soon. I greatly appreciate the details sir and keep them coming.
Wow! That Dillon is absolutely cool and i cant believe how fast the AMP is. I shot an 1.5" group myself at 1000y doing it the old-fashioned way with a drill, clock, a torch and a Redding Big Boss 2.
Great video, I’m glad someone did a detail comparison of the two. However the first piece of brass through the flame annealer was toasted a little longer than the others. You should have used a sacrificial piece of brass to adjust the time.
After watching LOTS of annealing videos by other reloaders I have a feeling that the way you've been doing it with the flame annealer is way better than the 750 degree tempilaq method. I would almost bet that you are not going to see much difference in your old method vs the AMP machine.
Hi Erick..I was looking for the one your using .The 1 with the turn table style..Couldn't find one so I went to the torch with the bottle and a drill.lol.I got it down pat works for me..I can tell just buy looking at it when it starts to turn blue the brass itself..I count about 8 seconds..
@Gabe Lackman What's the problem ??? My comment only refers to James's : usually Lapua puts 101 brass cases in their boxes instead of 100. When you post a comment it can be just an answer to somebody else's comment, are you discovering how TH-cam comments work ???
Lapua documents their consistency of their brass to 1% or less. That’s why they have 101 pieces because they are giving you the 1% for the inconsistent one you may get in a lot of 100.
Don Johnson I needed to anneal a batch of 70 6mmBR cases (using 0157 setting for the LAPUA SRP cases) and just for the fun of it, I timed myself to see how long that would take. I took 11 minutes and 10 seconds to do it. Granted, my annealer was on the bench, plugged in and all set up to do 6mmBRs so all I had to do was grab a bunch that already had the primers knocked out and have at it. i had thought that it would take longer than that, so I was quite surprised with the small amount of time it took! BTW, I completely agree with your assessment/comments on the use of calipers! I use decent calipers when I want to have speed, reasonable consistency and reasonable accuracy, so I DO use them quite a bit, but I DO use my mic which is somewhat slower but it gets me down to .0005" accuracy or better when I need it.
By the way I am using the salt bath for annealing. I'm pretty happy with how consistent it is. It beet the crap out of the torch and drill method. Probably not quite as good as the induction method though.
I have the same 2 annealers, & the only reason I bought the AMP was because I got it at an estate sale for $500 with 23 pilots. couldn't pass it up. Curious to see what further testing will reveal.
Hope your ready for a vacation to supervise the building of Matt's new silliness. I'm assuming you already know, but you can't tell Mere😂! God Bless you Sir!
Aware of some benefits in terms of material resilience, reduced and more controlled case stretching, when would the annealing of casings no longer be cost effective as it seems to have negligible influence of feeding and accuracy with bolt guns. Are all of these unique methods worth the additional labor? Although, one could admit the current 'F-class standard' of 1 - 1.5 inch 5 shot groups at 1,000 yards (courtesy Erik Cortina) is an indication of precision and quality control in every aspect of case preparation.
Erik my hands hurt just watching you pick up primers, you really to get a Frankford Arsenal Vibra-Prime for your pick up tubes, it'll change your life. Ask me how I know......
@Erik & FC John: Could I get your thoughts on a molten salt setup? It seems to me like a super cheap way to get 90% of the results: am I about right or am I out to lunch?
@@wilfdarr You realize the AMP annealer is not that much more precise then a flame annealer right? Even when tested with AMP's own AMP press. The only real advantage of the AMP annealer is not needing to use an open flame.
@@StuninRub Electric heating can be very precise, not that flame can't be, but you need good controls to get flame right, and those aren't going to come cheap. That said I think the benefit of the AMP is the ability to calibrate it automatically, not so much the precision. But for the price, I feel like salt annealing would beat similarly priced electric or flame annealers.
In all honesty, and saying this having a background in machining and metal forming, those first three from the flame annealer would not be different because of the annealing. As your sizing was done after the annealing and the first three to be sized are the only different from the others that is the strip that must be looked at by process. Your press is able to impart far more pressure than any slight difference in these annealing processes would be able to be affect. In my experience the first parts are always the ones to watch out for. Machines and tooling need to warm up. It very well could be (though I find unlikely) that your dies heated up slightly. It would be an interesting test to see if the first 5-10 pieces of brass measured the same as the last 5-10 of 1000 off a machine that had been running noon stop. It also begs the question as to the size of the dies on the production line somewhere like Lapua or Hornady. A die made of a larger piece of steel will take much longer to be affected by the friction of each piece whereas the dies for the reloader would be affected by heat faster, both heading up and cooling down.
The bench source is well made because you can fill it without waiting between each cycle. Is there some kind of automatic feeder for the AMP ? I also wonder if a flame annealer isnt worse because of the oxydization of the neck surface. There's just one thing I dont like with the AMP shell holder is that since you're holding the case on the bottom side, when you drop it into the bucket it falls on the neck... But it's easy to avoid it with a leather glove on your left hand.
I keep saying that I'm not a competitive shooter but I guess competing with myself counts. I use Ballistic Recreations annealing salt when I anneal. I don't anneal ever time but apparently I should be, I thought I had reloading figured out a long time ago. I almost feel like a beginner again. Thanks for taking the time to make these.
Hi Erik, You've helped inspire me to get into PRS...... somewhat off topic but what is the machine you used to engrave the brass? Do you have another video where you talk about your engraver? Also, although I'm sure you probably won't reuse the brass you engraved for competition shooting, do you think the engraving weakens the brass wall there at all, could it cause case separation? Thanks
Love your videos and the information Erik! Without seeing part 2 yet, I imagine that the flame cases are going to have less consistent neck tension. Honestly I think that the 8 second flame is too much for annealing. I bet if tempilaq was applied a double flame system would only need like 4-5 seconds to achieve that 750F point. Curious to see the next video! You rock brother!
Hi Erik, not seeing many people quenching the brass after annealing, and not much discussion. I would think this woukd be desirable to avoid softening of the wall near case head... thoughts?
All my reloading life (starting in 1967) I have used a pie pan or cake pan (I get them from thrift stores), Fill to halfway up the side of the case. put the rest of the cases in the pan, standing up. Get a popsickle stick. Heat the mouth of the brass with a pencil-point propane torch. Dim the lights. When the mouth glows, tip the brass over into the water with the popsickle stick and do the next one until all are annealed. This takes longer to read than it does to perform.Gather them up with my fingers and replace with un-annealed cases. Every other pan-full, replace the water with cold water and continue to march. Yes, it takes judgement to guage by eye the degree of anneal, but so do the other methods. As for "uniformity of anneal" I know the others ('specially the electric methods) are more uniform. But I feel I must keep the case head cool and never let the heat creep down to where the strength is needed. One soft head, even only one, will wreck the rifle and maybe kill or blind the shooter.
Another great vid Erik. Unfortunately it will be a minute before I can shell out for an AMP. I just have to do it on the flame anneal I built a couple of years ago. I do anneal as you used to; neck just turns red and they drop. I called EC Annealing. 😁
Thank you for a very nice video. However, prior to concluding that one machine is better than the other based on how the force measurements come out and how they shoot, you need to look at the times on the bench source; reducing the time or looking at a slight red glow or using tempilaq (yes this isn't perfect but something objective at least) prior to making a definitive statement. That 8 seconds is really cooking the brass. It may be the way you have always done it, but that doesn't mean the brass is ideally annealed and comparing it to the AMP is not apples to apples. I know you can't measure the molecular structure for the bench source the way the guys at AMP can and have calibrated their machine, but cooking the brass and then comparing it to the AMP isn't quite a just test. Your results at the range/competition is likely because you are a world class shooter, read the wind better than others, etc. I have both machines (bench source and AMP MKII) and they can give very similar results when using the 21st century hydroseater. No, this isn't the AMP force transducer, but it is at least objectively measuring something. Anyway, I think you are doing a great job, but I am just concerned about sweeping conclusions based on an incomplete test. Thank you.
Yes agreed! I have used a Benchsource for many years and one thing is certain, you cannot setup the machine and use it with a prior annealing time. The reason is simple, what affects annealing is heat, the amount of heat transfer to the case is affected by time, but also how hot the flame is, how far the torch is from the case, and where the torch is pointing at. One may be able to fix the latter two, but it is impossible to get the same flame once you have turned the flame off. As such, one must calibrate the annealing time each time you use the machine using the above mentioned method. Yes, I also agree that 8 seconds in the video where the brass is glowing cherry red is really cooking the brass and something to avoid...
Didn’t look thru all the comments as it may have come up but you can put the Amp in auto mode so you don’t need to keep pressing start making it even faster.
About use of AZTEC “from now on” - it’s not optimal. All it measures is a thickness of walls in the neck. With firings, brass flows towards neck. So AZTEC will change by a bit. I would test it after couple firings.
The problem with most induction Annealers is productivity. There’s a company Giraud that makes an annealing set up that can be adapted to use Annie Annealers brand power supplies and coils. It’s great because it’s auto feeding.
Eric Love your videos. I think you are the most no nonsense guy out there. I'm pretty new at long range precision shooting so I'm doing a lot of experimentation. I'm also an engineer so I have done some pretty crazy sh!# in the machine shop too. A little off subject but this question has been rattling around the back of my head. Full resizing. So I'm working with a 26 Nosler. I have been just neck sizing up to now. I have reloaded as many as 6 or 7 times on the same brass. So far I have not had a single sticky one, and have not even needed to trim. The brass fits perfect every time I reload. The question. Will resizing improve my group sizing? If not I don't see the reason to change anything. At this point I'm not competing either.
Have you changed the oil in your car? Was it still running good when you did? 😁 FL sizing is mostly for reliability, like your oil changes. Accuracy will be same or slightly better than neck sizing because brass will be more consistent fl sizing. Best part is that you won’t have extraction issues and your bolt will cycle easier.
@@ErikCortina Thanks Eric I haven't done any reloading since I watched your video on the subject. I was planning to go ahead with full resizing next time. I'm just stumped as to why I'm not getting any sticky cases or flow. Seems weird.
I am just surprised you didn't have a case feeder for your old annealing system honestly. With the wheel set up the way it is that'd have been super easy to add. Just a bit of Ready Rod, bracketry and some Lee Pro 1000 or similar parts I suspect.
Is it better to anneal before sizing/work hardening then seating into firmed brass or annealing after sizing then seating into soft brass thus brass has less grip on bullet upon firing ?
The only issue I see with the induction annealer other than trashing a few cases is that the case is inserted neck down...and since heat rises, more of the case body is getting heated. Is it an issue? Time will tell...
I have a question that might not make sense, so please excuse my ignorance. Should brass be cleaned first or after, sized before or after, does it make a difference? Oh I’m also talking about old way.
@@ErikCortina In my reloading I don't see much spring back in shoulder. Mostly in neck which is more uniform in shape. I don't neck turn so studies I have done testing for (5 sec, 10 sec, 12 sec, 15 sec and beyond dwell times) shows that non turned Lapua .308 LP brass requires at least 12 sec to set the resize dimension of the neck diameter (I use 15 sec for flame annealed). Just curious why you don't hold for neck dimension/tension.
I’m a bit new to this but you have mapp gas and propane wouldn’t you want to use two of the same cylinders for equal uniform heating or not so much or doesn’t matter?
Hey Erik, I realize this video is a couple years old now, but I have a question. You're using 2 torches, while my unit only has 1 torch. One of your torches is also MAP gas which is a bit hotter than propane. You're using 8 seconds, but if I was using propane and only 1 torch head wouldn't it take longer than 8 seconds???
(Looking at the gas barbecue grill on my patio) Hmmmm, that has a side burner on it that I never use. Gonna rig up something to hold and rotate my rifle cases over the flame...Viola! Annealed brass, and Midway can keep their pricey rigs, and I can keep my dough!
Great review but based on your previous videos the flame annealing was over annealed? Looking forward to see if the results have been pre-determined ;)
I'm amazed nobody has come out with a way to automate the Bench Source annealer - adding one of the collaters on the market (either Dillon or Hornady would probably work, or if you have deep pockets, M-A Systems) looks pretty straight forward.
@@ErikCortina Now I do the same, because I've noticed that the colored part of the case doesnt run smooth into the sizing die (cristals made by oxydization???).
No need to do that. When measuring the case we dont need to get absolute measurment (overall length in inches or millimeters), that's where calipers are a bit weak. Instead we need comparative measurments : how many thousands difference between 2 objects of almost the same size (2 cases here). Good calipers can give repeatable 1/2 thousand comparative measurments as you see in the video. That's why each time you need to use calipers un your reloading process, you should zero your calipers on a gage (a case, a bullet or a cartridge that you keep in a box) instead of relying on absolute numbers.
Erik, i am very impressed how deep you are going in detail and support us reloaders with all your experience. Very very worthful and not to find elsewhere. Thank you at this point
Came here to see the comparison, leaving with another reason I need a Fiber Laser Engraver. Thanks a lot Erik.

Curious to see the next video! You rock brother!
Thanks for sharing the video. Great information and comparison.
Hi Erik, not seeing many people quenching the brass after annealing, and not much discussion. I would think this woukd be desirable to avoid softening of the wall near case head... thoughts?
All my reloading life (starting in 1967) I have used a pie pan or cake pan (I get them from thrift stores), Fill to halfway up the side of the case. put the rest of the cases in the pan, standing up. Get a popsickle stick. Heat the mouth of the brass with a pencil-point propane torch. Dim the lights. When the mouth glows, tip the brass over into the water with the popsickle stick and do the next one until all are annealed. This takes longer to read than it does to perform.Gather them up with my fingers and replace with un-annealed cases. Every other pan-full, replace the water with cold water and continue to march. Yes, it takes judgement to guage by eye the degree of anneal, but so do the other methods. As for "uniformity of anneal" I know the others ('specially the electric methods) are more uniform. But I feel I must keep the case head cool and never let the heat creep down to where the strength is needed. One soft head, even only one, will wreck the rifle and maybe kill or blind the shooter.
I love what your saying here but you are selfish if you don't make a video showing what you described here.
Just ordered mine ! Can’t wait to get it ! Press too. Lol. Thank you for your video sir.
Facts and only the facts.
Another great vid Erik. Unfortunately it will be a minute before I can shell out for an AMP. I just have to do it on the flame anneal I built a couple of years ago. I do anneal as you used to; neck just turns red and they drop. I called EC Annealing. 😁
Thank you for a very nice video. However, prior to concluding that one machine is better than the other based on how the force measurements come out and how they shoot, you need to look at the times on the bench source; reducing the time or looking at a slight red glow or using tempilaq (yes this isn't perfect but something objective at least) prior to making a definitive statement. That 8 seconds is really cooking the brass. It may be the way you have always done it, but that doesn't mean the brass is ideally annealed and comparing it to the AMP is not apples to apples. I know you can't measure the molecular structure for the bench source the way the guys at AMP can and have calibrated their machine, but cooking the brass and then comparing it to the AMP isn't quite a just test. Your results at the range/competition is likely because you are a world class shooter, read the wind better than others, etc. I have both machines (bench source and AMP MKII) and they can give very similar results when using the 21st century hydroseater. No, this isn't the AMP force transducer, but it is at least objectively measuring something. Anyway, I think you are doing a great job, but I am just concerned about sweeping conclusions based on an incomplete test. Thank you.
Yes agreed! I have used a Benchsource for many years and one thing is certain, you cannot setup the machine and use it with a prior annealing time. The reason is simple, what affects annealing is heat, the amount of heat transfer to the case is affected by time, but also how hot the flame is, how far the torch is from the case, and where the torch is pointing at. One may be able to fix the latter two, but it is impossible to get the same flame once you have turned the flame off.
As such, one must calibrate the annealing time each time you use the machine using the above mentioned method.
Yes, I also agree that 8 seconds in the video where the brass is glowing cherry red is really cooking the brass and something to avoid...
I agree with you both, that 8 seconds in a twin flame is probably 50% too long, and brass should never change color to orange.
8 seconds is too much. 6 seconds is better. It doesn't glow red hot like that even when it's in the barrel being fired.
Didn’t look thru all the comments as it may have come up but you can put the Amp in auto mode so you don’t need to keep pressing start making it even faster.
About use of AZTEC “from now on” - it’s not optimal. All it measures is a thickness of walls in the neck. With firings, brass flows towards neck. So AZTEC will change by a bit. I would test it after couple firings.
The problem with most induction Annealers is productivity. There’s a company Giraud that makes an annealing set up that can be adapted to use Annie Annealers brand power supplies and coils. It’s great because it’s auto feeding.
Where's Part 2? I'm dying to find out if there is any appreciable difference in seating force consistency between the two annealing methods.
What happens if you skip this process and just load after trimming?
Eric
Love your videos.
I think you are the most no nonsense guy out there. I'm pretty new at long range precision shooting so I'm doing a lot of experimentation. I'm also an engineer so I have done some pretty crazy sh!# in the machine shop too.
A little off subject but this question has been rattling around the back of my head.
Full resizing. So I'm working with a 26 Nosler. I have been just neck sizing up to now. I have reloaded as many as 6 or 7 times on the same brass. So far I have not had a single sticky one, and have not even needed to trim. The brass fits perfect every time I reload. The question. Will resizing improve my group sizing? If not I don't see the reason to change anything. At this point I'm not competing either.
Have you changed the oil in your car? Was it still running good when you did?
😁
FL sizing is mostly for reliability, like your oil changes. Accuracy will be same or slightly better than neck sizing because brass will be more consistent fl sizing.
Best part is that you won’t have extraction issues and your bolt will cycle easier.
@@ErikCortina Thanks Eric
I haven't done any reloading since I watched your video on the subject. I was planning to go ahead with full resizing next time. I'm just stumped as to why I'm not getting any sticky cases or flow. Seems weird.
I use the Dillon 750 but without the automation. Checked on the cost to automate and backed away.
I didn’t buy the autodrive, I bought my own time back. 😉
I am just surprised you didn't have a case feeder for your old annealing system honestly. With the wheel set up the way it is that'd have been super easy to add. Just a bit of Ready Rod, bracketry and some Lee Pro 1000 or similar parts I suspect.
Is it better to anneal before sizing/work hardening then seating into firmed brass or annealing after sizing then seating into soft brass thus brass has less grip on bullet upon firing ?
I already know this video is going to destroy my ego about my annealing
Great detailed video. Thanks
The only issue I see with the induction annealer other than trashing a few cases is that the case is inserted neck down...and since heat rises, more of the case body is getting heated. Is it an issue? Time will tell...
Are those cases showing signs of case separation or am I just not looking at them correctly.
I have a question that might not make sense, so please excuse my ignorance.
Should brass be cleaned first or after, sized before or after, does it make a difference? Oh I’m also talking about old way.
Love the Dillon but why isn't the dwell working? Should be holding for 13 seconds. Don't you hold top dwell for resizing?
🤷♂️
As you saw, shoulder bump is consistent.
@@ErikCortina In my reloading I don't see much spring back in shoulder. Mostly in neck which is more uniform in shape. I don't neck turn so studies I have done testing for (5 sec, 10 sec, 12 sec, 15 sec and beyond dwell times) shows that non turned Lapua .308 LP brass requires at least 12 sec to set the resize dimension of the neck diameter (I use 15 sec for flame annealed). Just curious why you don't hold for neck dimension/tension.
when is the second video going to be posted I enjoy and learn from your videos.
Soon.
On your flame sneaker, why one propane flame and one Mapp gas flame?
Great stuff! Eric. When is part 2 coming?
Soon
Como siempre pura garantía tus videos
I’m a bit new to this but you have mapp gas and propane wouldn’t you want to use two of the same cylinders for equal uniform heating or not so much or doesn’t matter?
Can’t wait!
Thanks for the video.
Hey Erik, I realize this video is a couple years old now, but I have a question. You're using 2 torches, while my unit only has 1 torch. One of your torches is also MAP gas which is a bit hotter than propane. You're using 8 seconds, but if I was using propane and only 1 torch head wouldn't it take longer than 8 seconds???
That case trimmer really did quick work. Beats doing it by hand by a long ways
Does annealing help extend the life of the brass?
(Looking at the gas barbecue grill on my patio) Hmmmm, that has a side burner on it that I never use. Gonna rig up something to hold and rotate my rifle cases over the flame...Viola! Annealed brass, and Midway can keep their pricey rigs, and I can keep my dough!
I dig the quality tools. Mitutoyo are the best 👌
Now this is one REALLY wanting to see the out come
Question. Is your patreon $3,10,20 per video or per month. The patreon says per video..
Per video. I make one per week.
Lowest tier will be about $12-15 per month and so on.
Great review but based on your previous videos the flame annealing was over annealed? Looking forward to see if the results have been pre-determined ;)
Erik, What's the make of primer seating tool are you using?
I'm amazed nobody has come out with a way to automate the Bench Source annealer - adding one of the collaters on the market (either Dillon or Hornady would probably work, or if you have deep pockets, M-A Systems) looks pretty straight forward.
How did you go about marking the brass like that?
Does your trimmer also chamfer and de-burr?
When we gonna get the other parts to see results?
Why do you pause at the top of the sizing stroke?
So do you clean the brass then anneal then size it? Or can you anneal dirty brass then clean it then size it? Does it matter which order?
I anneal dirty brass.
@@ErikCortina Now I do the same, because I've noticed that the colored part of the case doesnt run smooth into the sizing die (cristals made by oxydization???).
Nice job done in the men shed 10/10
you used amp case #1 for your zero. What is your bump based on?
Erik is that a S type FL die with a bushing before the mandrel neck expander or is it a standard FL die?
Custom sized neck. No bushing.
If you want to know if your calipers are accurate to half a thousandth use them to measure your expander mandrels
No need to do that. When measuring the case we dont need to get absolute measurment (overall length in inches or millimeters), that's where calipers are a bit weak. Instead we need comparative measurments : how many thousands difference between 2 objects of almost the same size (2 cases here). Good calipers can give repeatable 1/2 thousand comparative measurments as you see in the video. That's why each time you need to use calipers un your reloading process, you should zero your calipers on a gage (a case, a bullet or a cartridge that you keep in a box) instead of relying on absolute numbers.
Does this mean your benchsource annealer is for sale? Price with and without autograph please.
Anyone know which FL sizing die and mandrel he has in the press?
When are the results coming?
What engraver do you have to engrave on brass cartridges?
