[QUOTE="3stooge, post: 1332550, member: 51456"] Well, the 28" barrel does explain a little bit as to why the vel is so high. But, with that said, it still seems like with that velocity you are likely over pressure. According to Quickload, it looks like max pressure would occur somewhere around 3,050 fps. Quickload did not match the velocity you are getting. It predicted 2,915 fps for your 81.5 gr load. Now, I just used an assumed water capacity for your brass so if the brass has less volume than assumed. It seems that your powder might have a burn rate higher than the default in Quickload. Even a 5% increase in burn rate and 82.3 gr charge is supposed to get 3,007 fps at just about max pressure. I hope this helps. If it were me, I think I'd look for accuracy below your 81.5 gr load.
