[QUOTE="live2huntmt, post: 1304005, member: 75903"] I just did a H2O capacity test...the fired brass has 3.6% more case capacity than the virgin brass. I had to reduce my loads 4.2%. the .6% difference could be the energy used to fireform the brass. I tried virgin brass yesterday and it shot approximately 22 fps slower than the once fired brass in my reduced load of 92grains. I completely cleaned the rifle and did not notice any difference in velocities or pressure after I fired 3 fouling shots. I have come to the conclusion that I was more than likely over pressure when fireforming the virgin brass, but the fireforming process helped mask the pressure signs. My reduced loads are producing the same accuracy at the same velocity that I had before..maybe even better. My ES and SD have reduced when using the reduced load in the fireformed brass. I appreciate everyones input! [/QUOTE]
