It's been quite a while since I had a larger cased .30. My short-range match rifle is a .30BR, but will handle 165'sd at about 2,450fps if I needed to use it for deer or BBear(I don't)
Am considering purchasing a .308 Ruger MK11 International from a friend. I have that rifle in .243 (purchased from him), but do miss the .308 round.

The .308 makes a wonderful addition to any battery.

I have no need nor desire for a .30 magnum - been there numerous times.

For long range big game, my .375 '06/IMP is sighted to 400yards - 200yards more than I'll ever need Here.
