This thing is awesome. In a small brief testing period of my own, it far beats out the V12. Less Powder, 115g Major, and much softer in hand. I do not have this barrel reamed by the good folks at PD yet. I was very anxious to test it out and quickly made up some loads I knew wouldn't touch major with a 115 from the V12, but Might with the Durso comp. Sure enough I made 166pf with 115g Blues over 7.9g of Power pistol. Loaded @ .....1.06. I can't wait to do more testing with a better powder and after reaming. Thoughts are on AA7.
