Worked on a load last night of 25.0 gr Hodgdon Benchmark, with a 55 gr JHP BT Sierra GameKing (not Speer) I took picture and then realized that it was not the Speer bullets but the Sierra bullets, so rather than re-take the pictures, I edited on the target and figured I'd just mention it in here. 100 yards, and 6 shots. Normally I shot 3 shot groups testing, or a 5 shot group for point of impact, but last night I ended up making one extra bullet, so thought.. what the heck. Group on the furthest holes measured 0.891" center - center. It seems to open up a bit more with an extra .5 grain of powder, and it could also be to the fact that I'm shooting hollow point as opposed to FMJ (same bullet mfg, Sierra). Another thing is these hollow points don't have a cannelure for crimping lightly, so I probably don't have an "exact" crimp as I did before.
I'm off a bit from the bullseye, but I had the scope and mount off of the rifle the other day, shooting with iron sights, and when I put it back on, I tried to adjust a bit down and over to the right from a previous target I shot and over corrected a bit on the down part, but the L-R windage seems pretty good.
