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.

@johnbladen4931 4 месяца назад

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

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!

@RejeanBoucher 6 месяцев назад

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.

@geoffkeeler5106 6 месяцев назад

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!

@markandsamafterwork 6 месяцев назад

@OldManMontgomery 6 месяцев назад

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.

@markandsamafterwork 6 месяцев назад

Thanks Man, Cheers

@michaelkaliski7651 6 месяцев назад

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.

@gb123-ej8wh 5 месяцев назад

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.

@ironDsteele 6 месяцев назад

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.

What I've noticed with my brass is more carbon present when using double-base powders, especially ball powders. So two ways to get around this is to use single base powders or nickel-plated brass. Besides that, everything was spot on. Great info!

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.

@georgedreisch2662 6 месяцев назад

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

@markandsamafterwork 6 месяцев назад

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

@johnpew6846 6 месяцев назад

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.

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.

@CMAenergy 14 часов назад

@@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,

Sooted necks is insufficient pressure to seal the case and powder fouling can get around the case mouth.

@markandsamafterwork 5 месяцев назад

@MrGsteele 6 месяцев назад

Two thoughts: obviously, if you are firing cast bullets, there's the issue that your mold could be producing undersized bullets that - when inserted in the case neck - are expanding the case neck insufficiently to completely fill the neck portion of the chamber, thereby introducing the space for the unburned gas to infiltrate before the case neck expands; too-soft lead, as well, can fail to expand the case neck completely or shear lead from a sharp neck edge when the bullet is inserted, if the case neck is inadequately flared. As for annealing, not only could the stiffer brass retard neck expansion, but also the dark residue could be used as a sign that you are running your case necks too hard, working the brass excessively, and thereby inviting split case necks - which, during firing, can present a safety hazard. So - like primer indications - that could be an omen that it's time to anneal or toss your brass, or modify/improve your annealing technique. It's particularly problematic if you routinely full-length resize, because split necks are less dangerous than a case head separation or failure elsewhere on the case body resulting from excess cold working. Interesting video; thanks for bringing the issue up.
