I have been out a couple times now with test loads, the rifle seems to favor top end pressures with both 4166 and Benchmark / 52 gr Sierras/ rem 7 1/2s .
700 VSSF / 6X24 Burris.
I have only shot 3 shot groups at this point, right at 1/2' MOA. I'll have to run a few more test groups to make sure it's the right combo.
