Re: What is annealing
I've never annealed a case. Full-length resized one Federal .308 Win. case about 45 times, using max powder charge, then firing it in the same rifle with a muzzle velocity spread of about 25 fps. The only thing I had to do was trim the case back a few thousandths about every 10 sizings. All 45 shots were fired in about 45 minutes.
So much for full-length sizing reducing case life and having to anneal case necks every so often.
