Hey all,
i've been handloading a few years (38/357, 45-70, 45 colt/ 454 casull, 30-30, 338 lapua ). Ive mainly focused my attention in the 45-70, 357 mag and 454 casull loading the other calibers rarely. Being straight walled cases i haven't annealed anything. Ive had the occasional split case but generally dispose of my worst looking brass after cleaning.
I bought 500 new starline 454 cases in the fall to replace a couple hundred federal cases that had been loaded maybe 6 times give or take. I size and trim new brass and found maybe 15 out of the first 100 cases you really had to apply considerable force to the press lever to size. Didn't give it too much thought but did note it in my book. 360 wfn gc bullets loaded with h110 and a remington 7 1/2 primer (same load i've used in all other brass including starline cases that were bought as loaded ammunition) . After my next range trip i sorted my brass and noticed a couple split cases. Seperated them out , cleaned the brass and resized. Noticed the same thing, the cases that were hard to size the first time were obviously still hard to size. Im fairly sure the cases that split were of that group too.
My question is , should i anneal these ones? Should i anneal them all? it seems to not be a common practice to anneal pistol brass like this. Should i just reject these ones? They weigh the same as the cases that are easily sized so i dont think its a thickness issue. I dont think its a pressure issue either, no pressure signs, felt normal, hit to POA.
Thanks for the input.
