- The purpose of this video is to display the effects of lubricating the inside of the case neck and bullet prior to seating. Utilizing lubrication in the neck and bullet leads to lower velocity, lower velocity standard deviation, and better precision relative to not using lube. It is recommended that shooters utilize lube as part of the bullet seating process for improved ballistics and precision.
Thanks, I was waiting on that video. I see better groups lubing the case necks. I shoot 300 and 600 yards IBS for score. As far as that flyer goes, I believe flyers are random and should never hit in the same place, such as low or high etc. if they are always in the same area, it's something with the setup or shooter. The flyer would be counted in a match, so it must be counted in practice. Thanks a bunch for these videos !!!
I've been doing ng this lubrication for almost 18 months.Its a good step.Great video.I don't have an Amp Press,just a K&M Precision Arbor Press with Dial Indicator for Pressure.I write down the results and it shows t he same info.The shooting with Labradar and Shotmarker also gave same results as yours. I did 20 and 20 bullet split.
I also had a couple flyers with one excessive speed.Dont know why.My V4 Auto Trickler & 120 scale is spot on
I am finding there are a few factors that can cause speed variations. One of them being primer weight…the heavier the weight, the faster the velocity.
@@WitchDoctorPrecision Bryan I sure did not know that.I will have to look into that.Im going to orider and Amp Press and Annealer.Its Been on my list. Just bought a V4 Auto Trickler and fx 120i Scale.
Getting a little more good stuff at a time.
The Century 21 mandrel helped my velocity and consistency and neck lube.Thanks for telling me about the primers.I use a lot of cci 250 on my 6.5 PRC And my 300 PRC.I never thought about weighing primers though.
@@WitchDoctorPrecision Bryan, How much variation are you seeing in primer weight? Also which brand of primers are most consistent so far? Federal? CCI, ??Remington BR ??? Thanks, Hope you had Happy Easter too.
@@TexasTrained usually .12 to .14 grains with BR-4, 450, 205, and 205M. The BR-4 and 205Ms seem to have more primers in the 3.66-3.68 weight range and the 450 and 205 seem to have more at the tail ends of the distribution - 3.60, 3.62, 3.72, and 3.74. Another thing I find is that some lots are way more consistent than others. Also, within a brick of 1000 primers, some trays of 100 are more consistent than others and sometimes a tray or two can be lighter or heavier than normal. All of this variation has me sorting primers as part of my reloading routine. It takes a lot of time but I do it while I am doing other things so it is feasible for me.
great video
I like lube in the neck to bullet interface for stability (I'm a hunting, XTC, and HP shooter, not a BR shooter so I pre-load my ammo). Occasionally you trip into adhesive friction and galling when similar nascent metals try to bond and stick. I can't explain my storage time factor theory, but storage time also seems to plays role and my hypothesis in that solid lubes can help mitigate this effect.
To phrase my hypothesis in simple terms, un-lubed will have a higher likelihood of erratic friction compared to lubricated especially when storage time is considered.
As a suggestion to get to the bottom of the benefit for a BR shooter, it becomes obvious that the load must be tuned to the two different conditions to get a fair look. I would suggest optimizing the tune for un-lubed and same for graphite before we would draw conclusions. If the very least the graphite did was to prevent adhesive friction from causing erratic neck tension, it would be worth the trouble for you. Thanks again for sharing the work.
Excellent work Bryan, I'm really liking what you have been doing. I moly (dry) the inside of the necks in an attempt to achieve consistent neck tension and to delay or avoid cold bonding. However, I don't want to deposit it (or graphite) in my barrel or have it effect the bullet velocity. Consider running another test with coating only the inside of the neck with Neolube. My expectation is you would get the same neck tension consistency with no velocity change and equivalent groups.
Another great video really enjoying your testing
I believe your fire came from a slightly inconsistent neck tension And slight difference and pressure I am using the neolube two as well and doing both components The extreme spread and standard deviation are the real clue to the story Keep up the great videos
The velocity changes match up exactly with my previous use of Moly bullets, always had to add .2 grains of powder to Moly rounds to match the velocity of my non Moly rounds
I had read about similar velocity differences in moly coated as well as hexagonal boron coated bullets. I have been using graphite in my necks on the recommendation of a very accomplished score shooter, and felt that the gun was much less prone to fliers allowing those x's to just pile up. With group I have not had enough time behind a ppc to know the potential yet, but I will find out!
Thanks for the test.
Exactly the info I'm interested in. I dry lube with graphite with the Redding graphite media dip. I'm interested in neolube as it seems cleaner, no graphite on case neck, and, consistent application amount as indicated on 'winning in the wind.
Can't find neolube in Australia....I do have graphite and alcohol though...🙄...but, haven't tried making any.
I'd like to see neolube vs dry graphite lube, Redding.
Doubt there'd be much difference though.
Many thanks for posting, again ..
Awesome stuff thank u
Thanks Bryan!!
Thank you.
Thanks for the video
Im not so advanced as you guys ,but I'm trying.
Well I built a machine that I fit on my press that will measure the force of each case as I put it through the mandrel and then sort them by numbers
Same goes with the seating
Have you measured and found any trends with your machine?
@@WitchDoctorPrecision yes I found that for example some cases are 1.5kg some are 1.8kg and then those big ones 2.6kg and those are tight neck tension
Have you tested NL2 compared to dry graphite on ceramic balls?
Please post a hyperlink to dry graphite on ceramic balls.
Bryan..another great video. How was the brass processes before this test? Was the brass annealed? Was the brass tumbled? I have been going back and forth between tumbling in rice in order to leave some carbon in the neck vs. wet tumbling and using a lube on the necks and bullets. Do you have any data on wet tumbled brass with lube in the neck?
Thanks for tuning in. I don’t tumble small batches like this. I dry tumble large batches because it’s too time consuming to wipe off the sizing lube from a bunch of brass. I never wet tumble and always leave the carbon in the neck. I have done a lot of informal testing and concluded that it is easier to tune with the carbon in the neck. I can always revisit this and do a formal test. Anyway, I wipe off the neck carbon with steel wool, wipe off the steel wool, brush the inside of the neck, anneal, and then resize. I am doing a test soon where I will be brushing the neck before and after annealing. Should be published soon.
What do you think about wet tumble vs not?
Hello Bryan - I am a long time reloader who has ALWAYS struggled with batch to batch consistency. I have recently redefined my reloading process with a focus on consistency within the process. My current thought is to wet tumble each time (also anneal), my theory is I start with the inside of the neck in the same condition (clean) each time. I'm thinking anything else is outside of being "controlled" i.e. how many layers of carbon are there, different powers leave different amount of carbon etc. My shooting is mostly related to hunting and plinking out to 500 yard's. So my question is the neck lube itself. You use Neolube, I am guessing it is suspended in alcohol and provides a very smooth even application. I want to know your thoughts on using case lube (comes in a tub and I am guessing is wax based) applied with a Q tip. Remember I'm not in any form of competition shooting just trying for consistency. Is there in your opinion any significant downside to using that?
I would try them both and compare. Some lines are better than others for certain applications.
Did you ever revisit this and try dry graphite with the neo lube?
No, have you tried that?
@@WitchDoctorPrecision I just learned about the neo lube from your video last month. I also don’t have an amp press.
@@justice1327 are you planning on using Neolube? One other thing I’ve noticed about it is if I have bullets I made but haven’t shot in months, there is no “cold weld” effect.
Hi Brian,
In this video, you state you lubed both the inside the case neck, as well the bullet itself. I am a mid-range bench rest shooter, out to 300yds, shooting .223 Remington. I load the Berger 55gr FB Target bullet, which is short in OAL. While lubing case necks is not a problem, being able to lube the bullet is difficult at best, again given the length of the bullet.
Do you have a suggestion as to how I can efficiently lube the bullet, or how about the possibility of only lubing the inside case mouth.
I would use liquid lube and either dip the bottom of the bullet into it or dip a swab and then brush the lube on the bearing surface.
@@WitchDoctorPrecision Thanks for your feedback. i believe the biggest challenge will being able to hang onto the little bullet while lubing. :)
@@timfarley6493 yeah, with bullets that small it will be hard. If it becomes too much of a burden then at least lubing the inside of the neck is better than no lube at all according to the data.
Hi Bryan: Did you anele and brush before you started this test?
Yes, brushed and then annealed before size and seat.
Great stuff. Was the brass annealed?
Yep
