[QUOTE="Bigeclipse, post: 1928051, member: 52437"] ok to confuse things worse....The two loads I shot yesterday were 3209fps and 3220fps. These were 79 grains and 79.2 grains. 79.2 grains I got a nice ejector mark, with stiff bolt lift, cratered primer and I could feel the load was a stout load. Here is where I am confused. Today to check everything everyone was saying, I resized the brass, picked out all the ones that chambered well in my chamber, retrimmed going .010 shorter than before AND seated the bullets .010 deeper, which in theory now I am .030 off the lands instead of .020. I loaded up a 79 grain and a 79.2 grain load. Shot them both. NO ejector marks. No stiff bolt lift and no cratering. Basically no signs of pressure BUT the velocities matched yesterday. I got 3206 on the first shot and 3219 on the 79.2 grain load. So one of the things i did obviously changed something lol but now I don't know what haha. What I am confused at even more so is that whatever I did must have lowered the pressure and typically lower pressure means lower velocity. I am now wondering if maybe that shot that had the extreme pressure signs yesterday had something wrong with the load. Bullet not seated deep enough, case not trimmed so it pinched the bullet. Time to pull all the bullets and start over. [/QUOTE]
