    @MrNeverlost1 11 หลายเดือนก่อน +23

    I had an unusual issue with a 6.5x284. It was at the end of it's life at 1200 rounds. Cases were indicating low pressure (soot all the way to the rim) and high pressure (stiff bolt and shinny ejector swipe) at the same time. My theory is the very worn throat was not allowing pressure to build up until the bullet traveled a few inches then the bullet stopped until rapidly building pressure got it moving again. I've never seen that before or since and I've been reloading 50 years. Replaced the barrel with no further issues.

      Yes, I had a very old 30-30 passed down to me and a normal 42k psi load would blacken but a 165gr Hornady boat tail with a stiff load of 4198 would not (the same load I used in my Contender). Incredibly it was very accurate. Annealing is also imperative.

    Thanks Mark great explanation. As this residue is more like soot than baked on carbon, what I have been utilizing is a very small amount from a product known as Ballistol oil spray on a rag/tissue and then I just rotate the neck onto the rag, usually only requires one or 2 turns of the case; no scrubbing and necks come out spotless.

    Funny you did this video just a week after I was trying to explain to a fellow shooter at my club. Will forward it to him as you explained it in greater detail. 👍👍 His issue is he might be over sizing the shoulder bump a bit too much as the carbon burn is also down the sides of the case.

    Another excellent explanation Mark.. Thanks. I've hand loaded everything for two barrels in my 6.5 X 47L. Last summer I purchased factory Lapua ammunition for the first time ever for this caliber. The fired rounds came out perfectly clean at the neck! Which I scratched my head over. Im guessing the factory stuff was crimped. It grouped very very well but was almost 100 fps slower than my handholds with the same bullet. So I have lowered velocity in my handholds and they group amazingly!

  • @paulharding1621

    Great explanation of the issues and reasons for sooty necks. My 6mm REM Ruger No1 always gives slightly discoloured necks. I use full charges of RL22 which is on the slow side but with 100gr bullets I get half MOA groups so I’m not too worried about the neck colouration issue.

  • @gb123-ej8wh
    @gb123-ej8wh 10 หลายเดือนก่อน +1

    I have had low pressure cause gas to move past the bolt and spit in my face. The answers are as you mentioned increase pressure and or soften the brass by annealing it. Driving pressure up can be done by crimping, by raising the charge and by reducing case capacity via use of fillers. Fillers also keep charge pushed against the powder.

  • @Fatman131
    @Fatman131 11 หลายเดือนก่อน +9

    Thank you Mark, I’ve been having this issue for a while, particularly with ADI brass even after I’ve annealed it. It seems to be a very fine line between dirty necks and clean but with signs of pressure. Your video has really given me something to work with, thanks so much.

  • @johnbladen4931
    @johnbladen4931 9 หลายเดือนก่อน +5

    I agree Mark. For peoples info, I believe you need to remove this black soot (Carbon), off your cases, prior to resizing these cases. The reason I suggest this is, this Carbon (on your cases) is actually harder than your steel of your reloading die, so it can actually scratch the inside of your resizing die. So, how do I remove this carbon? I wipe it off with a clean rag, or if there is a lot of carbon, as you suggested, I also use a well used/worn 3M Scotch Brite pad, that I have on my reloading bench. Hope that helps. JB

  • @Gunner-73
    @Gunner-73 2 หลายเดือนก่อน +1

    Thanks for sharing. When I started reloading, 1981. I couldn't afford a rifle. My monthly income was $309. Yep, Army pay. I started working a second job on the weekends and after hours. It all helped. After about a year, I bought my first large rifle, Inter Arms Mauser, Mark X, 30-06. That was my learning rifle. I later bought a single stage RCBS press and thus begun my reloading. Annealing wasn't a big thing back then, but the black soot at the case mouth was. I certainly did split a few case mouths after 10 or so firings. Then I started annealing. At that time, I was only concerned with shooting out to 200 - 300 yards. It wasn't until I started out to 500 yards that I started paying attention to neck tension, bullet seating depth and annealing. At that time, 500 yards was a long shot, but now its like a chip shot. Now, everything plays a part, powder temp, neck tension, powder burn rate, Ojive, Flat base vrs boat tail. I met a guy at the range, Fort Carson Colorado. When he pulled the trigger, it was a large boom. So I paid attention to his next shot. He had prepared his brass at home, cleaned resided and primed. At the range, he would dip his 300 Win Mag brass into a tub of powder till the case was full to the neck. Hand seat a 180 grain bullet with his hand press, load and fire. Thats how he loaded his ammo. That was 40 years ago and I have not forgotten him. Not that I follow his lead, cause I didn't. Anyway, I enjoyed your video. Thank you to share.

  • @michaelotto8696
    @michaelotto8696 4 หลายเดือนก่อน +1

    I've put some of this down to powder burn speed. Slower burn, black necks. Faster burn, clean(er) necks. This also affects pressures. Thank you for this content! 👍

  • @geoffkeeler5106
    @geoffkeeler5106 11 หลายเดือนก่อน +2

    Very well explained Mark. Personally I never experienced this phenomenon much when I was shooting, but then I was using the notoriously high pressure.45 ACP! Seriously though, speed of initial pressure rise, neck tension, even things like bullet inertia will affect all of this, as you explained. Thanks for another good video!

  • @OldManMontgomery
    @OldManMontgomery 11 หลายเดือนก่อน +1

    I have experienced the gas 'blow by' to discolor brass. I long ago figured out it was 'blow by' doing the effect. However, I didn't realize the lower beginning of the powder charge the effect happens. Good information and good video.
    Slower powders are more prone. I prefer slower powders in my rifles to accommodate heavier bullets. I can live with more careful cleaning. I do anneal rifle brass every five firings or so.
    Thanks for the real information.

    Completely makes sense to me. I see the carbon discoloration on the necks of my 300 Weatherby much more than I do with my tight-chambered 270WSM. The Weatherby has some freebore in the throat where the WSM is usually right on the lands, depending on bullet I'm using. Great video, as always!

  • @michaelkaliski7651
    @michaelkaliski7651 11 หลายเดือนก่อน +1

    A great explanation and details. Perhaps worth mentioning that perfect seals around the bullet and cartridge are impractical otherwise it would be impossible to load and unload the gun, let alone fire a bullet along the barrel. There will always be some small gap where high pressure gas will blow by.

  • @ironDsteele
    @ironDsteele 11 หลายเดือนก่อน +1

    I've had overly sooty cases from using powder that's too slow. For example, I once loaded 55gr FMJBT in the 5.56 NATO using VitaVouri N135 powder. The load was as compressed as I could make it and they were heavily crimped. I had soot all the way down the side of the case onto the case head and covering the primer on some cases. I knew after firing a few this wasn't acceptable and I couldn't keep shooting them but here's the interesting part. The load was superbly accurate and the ES was pretty good. My velocities were around 3050 fps out of a 16.5" carbine. Thanks for covering this topic, I haven't heard it discussed in this detail before.

    I had it experimenting with magnum primers in a worn out 243. Powder shortages in the UK so I was using Ramshot Hunter (ball) powder. 243 barrel after 4000 shots was probably smoothbore for a fair bit but the same load with standard primers wasn't as bad.

    Yep! I agree as to crimp versus non crimp, I had an issue and realized it was also head space and slight carbon buildup on an old 30-06. My brother borrowed my rifle and when I got it back was when I first noticed it but he also ruined rifles crown because rifle never shot the same. I went from a sub MOA to bullets all over the place.

    I like to use H4895 for reduced recoil loads in my 300 Weatherby. I can plink all day long using that power and 150-grain bullets, but if I go too low, the necks will not seal, and soot will blow back all the way to the belt. If the soot is too thick, it can be difficult, if not impossible, to remove. It seems to impregnate the brass.

  • @tlloyd9325
    @tlloyd9325 2 หลายเดือนก่อน

    I have been resizing my brass to the point that I just barely engage the shoulder or the sloped part of the case just aft of the neck. This has seemed to help even if I’m using a powder that might not burn efficiently. I rely on the lowest shot to shot deviation. That usually gives me the best groups.

    Is it possible to not resize your brass and just fire form it? If you are using it in the same chamber. Would that solve seal problems without compromising accuracy without causing stuck cases? Would that also possibly reduce the need for annealing the brass since it would be worked less?

    I have done a bit of machining in my life time,
    Basically I would say your skirting the main problem
    If gasses are escaping back at the neck of the brass,
    Then I would say that the chamber of the barrel was made a little on the lose side
    But who am I to say, since i'm no exert gun machinist
    But when brass comes out clean,
    I would be pointing my finger at the chamber.

      if you're shooting once fired brass from the military every full automatic weapon has huge chamber clearance sometimes as much as 0.015 clearance. bolt action rifles have usually less than five. resizing with full-length dies after using 556 from military ranges it never gets stressed that much again.

      @@willfriar8054 Yes I would agree, because temperatures rise radically and that changes tolerances and can tighten and loosen where it should not be
      And that may also be a reason why bullets get sprayed every which where when rapid firring is in place and many targets get missed except at close range,

    My custom built falling block chambered in 223 does this with 4198 but still has produced some five shot groups in the .2’s 3’s and will average 1/2 inch 100 yard groups, so while informative it’s not a big deal.

    Have a little short barreled savage 110, chambered in 7mm-08 .
    This particular rifle has done this since day 1 .
    Does it with factory , and hand loaded rounds, seems like it likes certain brass better than others?
    The little rifle shoots excellent, so never let it concern me much, just clean it up and move on.

    The brass case becomes a seal. It must be consistent in sealing the chamber to keep the gas from escaping through the bolt side of the breech which helps in consistency of your accuracy.

    Hi, Mark and thanx , I now understand why I also suffer of blackened case neck,uh... matter of fact I never crimp my reloaded ammo, so I guess this must be most of the problem, which, in my opinion ignites another problem about the crimping torque.. in order to have it even, is there any DYNO that you can screw on the press shaft.. ? I think it were no bad idea to have one.. hi

    • @markandsamafterwork
      @markandsamafterwork  11 หลายเดือนก่อน

      Lots of options other than crimping, but as said, if all good otherwise, a little cleaning is not a concern, Cheers

    With a 300PRC w/N570 I got good performance but horrible soot - H1K, retumbo, N565 were all good. But in a 300NM w/same powder/primer my barrel/chamber were nicely clean.

    Not to knock your statement of gas getting in front of the bullet as shown in your high speed video. I’ve found it also to be common, and especially with surplus guns, to have the rifling eroded at the muzzle. I suppose this is the result of repeated cleanings, sawing with a steel rod, from the muzzle. This is easily found with gauge pins, and remedied by moving the muzzle back the distance of the length in the wobble of the gauge pin and recrowning.
    I brought this up, as I suspect it may also be a factor in the gas getting ahead of the bullet, in your high speed video.
    Thanks for sharing.
    Cheers

      Crown has a big effect on accuracy, but no effect on the necks an little to no effect on gas getting in front of the bullet, but yes that is a way to fix a poor crown, Cheers

    I always see this kind of blow-by in my hand-loaded 45 Colt cartridges. They have usually very little propellant in them (originally a black powder cartridge) and almost the entire case is black after firing.

    Could I ask if you have discussed bullet jump / gap to the lands? Is this a somewhat standard you use with your loads?

    There’s a product called carbon killer that works well for this. Been loading since 70’s and never gave it much thought, just tumble my brass and keep chamber clean. I’ve gone on several trips shooting prairie dogs shooting 3-400 rds a day for 8-10 days and clean bore every 40-50 rds and have never had any issues.
