I was wondering what's the better ammo out of these 2. I've shot maybe 400-500 rounds of TULA and I've had like 10 cases seize up in my chamber. I shot 40 rounds the other day and then they started seizing up one after the other. Maybe my barrel was getting hot. The Brown Bear was good but, its laquer coated and I'm not for sure if that's good to shoot all the time. ANY INFO WOULD BE GREATLY APPRECIATED. THANKS FOR READING.
