elmer- if velocity is your goal I would look at slower powders for the 160's and up. I couldn't get great speed or accuracy w/ R-22 but average around 3100fps with R-25 and 160 Accubonds in my 26" remy. They shoot sub moa too.

69.5 grs av speed 2988
70grs av speed 3050
all speeds were averages of 4-5 shots. As far as pressuse signs all I saw (with a magnifying glass) is some very slight cratering but primers were not flat at all bolt was fine and the cases were neck sized. My last group was under half inch. I will test this load some more but so far it looks real good.
