Not good. I reloaded 48 rounds with the following formula: Alliant Bullseye/185 gr Flat Nose/4.3 gr/Remington Large Pistol Primers Lots of failure to eject and stovepiping issues. A few failure to load. The accuracy was good and the recoil was way lower than with the Federal 230 FMJ I have been shooting up to this point. I fired 4 mags of factory ammo first and the gun (SA 1911) ran flawlessly. Also had this: Fairly sizeable burn on the brass. Would this be due to a weak crimp? Will increasing the powder solve the ejection issues? This gun usually send it flying several feet and my reloads had it basically falling at my feet. The max for powder is 5.6 gr according to my Lyman manual.
