I’m phasing out Rifle powders now.
I'm doing the same thing with pistol powders. Unfortunately, I haven't been loading a lot of pistol, lately, because I've been concentrating on case prep and ladders in .308, 6.5CM, and 5.56mm.
To that end, I started sorting and counting what I have on hand as far as 5.56mm ammo and components. I decided some years ago to slim down my 5.56mm brass to only LC, which I have a bunch of, and the very little PMC, that I would use for accuracy loads. I went ahead and counted all of it (by weight... I'm not counting each of those little buggers...) and sorted the 1000+ cases I had in the 'fired, mixed' bin. I tumbled down all of the .223 stamped brass (FC and LC... yes, LC kicked out .223 stamped ammos...) and set that aside for the FS/FT thread. I have the remainder stacked on the bench for sizing, and then processing... they will require the primer pockets to be cut.
Staged the .308 brass on the loading bench, and set up the trimmer... I figure if I can trim 100 cases each evening, I... a) won't get
rigor mortis hands, and b) will actually get the brass done in a reasonable amount of time... 500-600 cases each week, 2000 cases in a month, to include primer pocket cuts, and chamfering the case mouths after trimming.
I did set and probe all of my M1a segregated 7.62mm cases... LC and nny Prvi cases... looking for case head separation indicators... about 500 cases. Didn't find one which is interesting considering the nearly 20% failure rate I found with my last batch of LC. These cases are in that same lot (LC18,) so thinking back, I would guess that those cases only have 1 firing on them... the bad cases I found had 2. Still a pretty poor turnover rate, but I FL size my brass so everything fits everything.... I guess I'm paying the price for that, now.
What are you fire-lapping?
