I stopped picking up tula brass brass becouse it did it so bad it didnt even wana fit in a lee FCD without it trying to resize it,the bulge was so bad on one side. That brass seemed alot stiffer than FC or other range p/u brass. I havent tryed tula brass brass since to see if it still did it.
I know you guys dont trim pistol brass,i trimmed it trying to figure out this problem. It does take a lot of time…lol
