[QUOTE="JohnyRingo, post: 2225785, member: 100050"] Where should I go from here? 300 H&H Mag. 180 grain Accubonds. 67.5 grains of IMR 4831. CCI primers and Nosler brass. 3.652" OAL to lands. 3.585" OAL. ES=100 fps. 1.5 MOA (3-shot group) 3.595" OAL. ES=25 fps. 0.9 MOA 3.600" OAL. ES=15 fps. 0.7 (2-shot group and a big flier) 3.605" OAL. ES=14 fps. 0.8 MOA 3.613" OAL. ES=47 fps. 0.6 MOA 3.625" OAL. ES=25 fps. 1.18 MOA 3.640" OAL. ES=14 fps. 1.15 MOA Obviously, the 3.613" created the best group. I am surprised it shot so well with the ES being 47 fps. Should I try any other lengths to try to get better than 0.6 MOA? I am kicking around trying 3 shots at 3.610" and 3 shots at 3.620". I don't have a big surplus of reloading supplies to be messing with load development without eating into my supplies a little. This is the first time I have ever messed with seating depths as my other rifles seem to shoot great with advertised OAL. The advertised OAL for this load is 3.600", but I got a huge flier (2") out of it. [/QUOTE]
