I missed last week due to the holiday (Easter, which our family celebrates) so I was a little off today. I know that I need to get back to dry firing again on a more regular basis, which I have been neglecting due to other wifey duties. I fired 50 rounds of .45ACP with 6.9 grns. Power Pistol and 50 rounds with Titegroup. After firing approx. 500 rounds of each powder, I really believe that the Titegroup is a better suited powder for my RugerSR1911. Groups tended to be about 1" tighter. When loading Titegroup I use 4.6 grns. and always use Berry 230gr. RN. COAL runs between 1.250 & 1.255 for both powders. I also believe that Titegroup is a cleaner powder in burning and cleaning up my pistol when done. I still have 3lbs. of Power Pistol so I will eventually use it up as most of my shooting is plinking paper and then I will dig into my 7lbs. keg of Titegroup. I am sure some may differ on their opinion which I respect as this is just MHO. I would gladly trade my Power Pistol for W-231 or HP38. But as it turns out, any day at the range is a good day!!!!
