Brian,

With the 7x65R, seems you could regulate for the 175 grain bullet and, if it's a Swift A-Frame, be OK for most anything a 30-06 could take. With the rule of 3/4 you are also likely to regulate a 130-140 grain bullet as well using the same powder charge as for the 175 grain bullet (would shoot somewhat higher but that's not necessarily bad if you are shooting at longer range with a lighter bullet).

Best of the Season, Tim
