I'm working up loads for a 30-06 sporter. I tested loads yesterday with IMR 4350 and charges from 56.1 to 56.8 grains pushing the 155 grain A-Max. My best load was at 56.5 grains yielding a three shot group of .372", C to C, at 100 yards in a variable 10 to 15 mph wind. The A-Max was seated .042" OTL. I did prep my brass by uniforming the primer pocket, deburring the flash hole and trimming all brass to the same length.

Another test shooting four groups of three will determine if the initial results were a fluke. I let my barrel cool about two minutes between 3 shot strings. If you get consistent sub MOA 3 shot groups, I'd stick with that load for hunting.
