I finally got my 30-06 back this week, and my question is what grain bullet should i use w/ this gun. My 7mm-08 im shooting winchester 140 grain ballistic silvertip. My .308 im shooting 180 grain core loct. Now what grain would be good for the 30-06, Im debating between 180 and 220. This gun is going to be mostly heavy cover and brush hunting gun when im up at camp hunting in the blowdowns.
