Went ahead and backed my case OAL down from 1.270 to 1.230 and loaded up some charges using Hodgon HS6 at 8.2, 8.4, 8.7, 9.0, (ten of each) and 9.3 (five rounds of this) grains of powder for a 230gr hornady XTP bullet. Out of 45 total rounds fired, I had one get stuck as mentioned in the previous thread, and again had to have a friend work the slide while i held on to the gun to eject the round. I also had two rounds that would not go off because my gun failed to go all the way back in to battery. Any thoughts on this? Ive literally loaded thousands of .40 rounds with out one single malfunction, idk what my problem with .45 is. Also here are my chronograph results: 10 rounds loaded with 8.2gr of HS6 produced the best standard deviation, at 14.3 Unless you count the 5 rounds I loaded up at 9.3 grains which produced a standard deviation of 4. After seeing this, I wish I had loaded up 5 more. Here is my original thread for reference: http://www.glocktalk.com/forums/showthread.php?t=1353767 Wanna kill these ads? We can help!
