C T -
Over the years I have cut a bullet out from under the hide a few times but not many. It is very unusual for my rounds to NOT exit. Now I normally use 100 gr 6mm; 130 gr 270; 139 gr 7mm RM and velocities 3100; >>>3300 (7mag).
I'm down to my last week of M G deer season + 3 days after Christmas. This past week I only hunted Tues AM, we've been too warm & windy.
I plan to hit it hard this week.
