    Groups are to small

    So, what did you group measure that you got at 300 yds.? At 300 yds. I'd consider a "good group" to be ~1.5" or less. An ES of 138 and an SD of 36.7 is pretty bad, in my book. I once had an 50 shot ES of 97 with an SD of 33 when testing a new primer. That was the worst I've ever gotten...

    Black wavy marks on brass

    That's been my experience too, where 30 mins or less without pins (particularly in hot water) cleans cases up nicely. I don't know why some think they have to go for hours. In an experiment, I found not much tumbling has to be done at all. Just soaking the cases in the hot water solution...

    Black wavy marks on brass

    Wet tumbling without media does leave some of that carbon in the neck. But usually not enough is left for decent lubrication. Whenever I wet tumble, which is on rare occasions, that's how I do it when I've got a bunch of brass that's got a bunch of dirt, mud and grim inside, then I'll wet...

    Black wavy marks on brass

    But, I and many other's don't want in inside neck surfaces to be so clean. 😵‍💫 That residual layer left after firing acts nicely as a lubricant where having an extra step in the process for lubing in necks isn't needed. And in the case of rice, it can actually add additional lubrication.

    Black wavy marks on brass

    Hmmm??? "Most desired" depends on the objective and cost. :rolleyes:

    Will this brass still make accurate ammo

    That's what I thought when I saw that for the first time and thinking I should also see something like that on the bearing surfaces of pulled bullets. So I pulled some bullets to take a look; bearing surfaces were as smooth as they were before seating with no signs of galling or scrapes. If...

    Effects of case volume

    31 grs difference is a very very large difference, even for a 338LM. It's not unusual to have some difference from one headstamp to another or even from one lot to another of the same headstamp. I've not got any experience with any 338's, but it's like with my .308 when comparing PPU brass I...

    Will this brass still make accurate ammo

    I do not. I let my dry tumbling do the minimal cleaning of the neck's interior.

    Will this brass still make accurate ammo

    I've seen the same kind of thing on the inside of my brass necks, but not near as pronounced. I've never seen or felt anything on the outside of the neck and none of mine have looked like that right after firing. After firing, it just looks completely coated with burnt powder residue. I do...

    Black wavy marks on brass

    I've been using rice for many years and have not seen that on any of my cases, but I might make a guess: You're rice has been used a lot and is really dirty now; need changing to new rice??? A picture of the rice you used would help with the diagnosis. Those particular cases have more lube...

    Herters white/red box 243 brass?

    Various Herter's ammo is still being produce (mostly made by Winchester to my limited knowledge) . . . not necessarily known for quality ammo. I've used some their ammo and it was cheap ammo and I got what I paid for. . . poor results. That doesn't mean that the brass can't perform well, but...

    Thanks. They've updated it since then to include the new projectiles.

    Primer Sorting for Precision Loads

    Hmmm??? Are you saying you're seating the primers .004 below flush? And a height of .121 would make your pocket depths at .125"? To have an idea of how much the anvil is above the cup, keep in mind that the cup height of the CCI 450's is ~.113". If the cup measures .121 above the base of...

    .308 Winchester

    The objective that led to its design of the 277 Sig Fury was the military wanting a somewhat smaller round from a somewhat light maneuverable gun with a projectile than can penetrate body armor at distance. Also, part of the idea was smaller cartridge for the amount of velocity reducing the...

    .308 Winchester

    Certainly, case volume is going to be more after firing than a sized case. And in .308 the difference, I find, is about 1.5 grs H2O. . . depending on the thickness of the case walls. In my gun, the Lapua Palma brass performs just as well and more often better than Lapua LRP cases. But then...

    .308 Winchester

    Having necked up my 277 Sig Fury Hybrid cases to .308 with case volume of 57.7 gr H2O, this morning I tested some H4895 behind some 169 SMK's. Using data for the lot of powder that I had, the velocities came in really close to what QL predicted for me (about 8 fps higher, I think because it was...

    Primer Sorting for Precision Loads

    Yeah, measuring the heights are definitely a PIA, and likewise I'd sure be interested in finding an easy button to do it. In the meantime, I just use a caliper (my dexterity is still good enough at my advance age, fortunately ;)). If you haven't already seen this video, maybe you'll find it...

    Primer Sorting for Precision Loads

    I take measurements of the primer heights (only a sample size of ~10, so not all of them) and right the range on the packet of 100, which is typically in a range of .002 to .0025. I also uniform my primer pockets and know the depth of the pockets so I know how deep to see the primers in the...

    Brass Work Hardening Analysis by Alpha Munitions

    :LOL: :LOL: While I've compared thousands of different loads and rounds from not annealed to those that have been annealed, it's not been a waste of time and money for me. Like I mentioned, whether it's worth it to someone else really depends on the chamber design along with sizing dies and...

    Brass Work Hardening Analysis by Alpha Munitions

    As I've always pointed out, the big issues about annealing vs not annealing is how much is the brass being worked during the cycle of firing and sizing. If a chamber and sizing die are customized to where there's very little movement going on during this cycle, then one can do just fine without...
