Thanks for all the responses... The load data is for a 5" barrel with 1:16" twist using Federal 150 primers.... I am using CCI 300 primers and shot my reloads out of both my XD45 tactical with 5" barrel and my 1911 with 5" barrel. The results were very close. I also tried some factory ammo and was getting over 800 FPS so I dont think it is the Chronograph.
I have loaded around 1000 rounds so far and this was the first chance I had to chrono any of them. I will be using these loads for USPSA, so I was concerned when I realized I wasnt making major power factor. I guess I will see if I can get another Chrono to use, otherwise I will just continue to work up the loads until I get to where I need to be. Of course I will keep looking for signs of pressure. I was concerned because the max load is 5.3GR and I am at 4.5 and my velocity is alomost 100 FPS under the Minumum load velocity.
Thanks again for the replies.
