[QUOTE="Evilsports, post: 2289193, member: 40834"] Well this load has been nothing if not a wealth of learning for me. Just when it feels like I'm onto a load, a new variable pops up and sets me back a bit. Figured I had things dialled in fairly well as far as charge weight goes. Went to test at the range yesterday morning and could not hit a group again. Noticed that with the exact same weight (58.6gr) of H4831 I was getting muzzle velocities averaging 80fps higher than last weekend. The only difference was that I had previously been using up powder and primers that were a decade old. These new supplies were obviously running higher pressures than those old ones. I came back home and loaded up some lower test weights (57-58) and my groups tightened up to right around a minute back at the range. My velocities were still higher than my tightest groups from the previous weekend, so this morning I'll load some increments from 55-57gr and see if they tighten up further. [/QUOTE]
