(OVERWHELMING) Majority of my pistol brass is range pick ups whether picked up by myself or bought from others in bulk.
There's not as much risk re-using straight walled pistol brass since there's generally less pressures and no shoulder to stretch out thereby thinning the case.
Rifle brass I've used a few hundred range pick ups but you've got to be careful with those. Especially some of the .223 or 5.56 as many are shot out of semi auto loading rifles with generous chambers. Lots of case stretch can happen there and life expectancy can be greatly diminished.
I once bought 1,000 once fired 308 cases for what I thought was a decent price. After processing them I wasn't so sure. They took an extreme amount of force to resize on a single stage rock chucker press. I determined they must have been fired out of a very loose chambered machine gun. Accuracy was difficult to achieve as I had inconsistent neck tension and hard brass from being overworked in the loose chamber.
That batch caused me to wind up spending a decent amount of money on an AMP annealing machine. However, the subsequent brass resized with a lot more ease and consistency and the group sizes shrank quite noticeably.
It was quite the learning experience, albeit a somewhat expensive one.
