HC..I just recently started powder coating and shooting them. So far I've only shot them out of my Marlin in 35 Remington but they shot just as good as jacketed bullets and no fouling. Next test is gong to be full bore conicals in the muzzleloader. I have enough pistol ammo loaded through years of snowywinters where I passed the time reloading that I will never have to cast any bullets for them.
