Tried 190 grain hard cast bullets, 200 grain Hornady XTPs, and 200 grain Speer Gold Dots. All were tested with Accurate #9 and CCI standard large pistol primers. All were able to achieve my goal of 2" or better 5-shot groups at 25 yards, with a rest. But the loads using the Speer Gold Dots were just amazing. I achieved the smallest group I can recall ever getting with a defensive pistol at 25 yards. 3/4". Did a video of the range session on my YT channel... Achieving such accuracy with 620 ft. lbs. of energy in a concealable pistol with 11 rounds of capacity seems pretty amazing.
