Go here and do some calculations.
Do some playing around and see what comes out.
Experience says my 338 Win w/225gr bullets @2850 in 8 lb rifle w/decelerator recoil pad and tee shirt hurts [img]/ubbthreads/images/graemlins/shocked.gif[/img]
Same rifle at 10 lbs is fine [img]/ubbthreads/images/graemlins/smirk.gif[/img]
7mm RUM w/140 gr @ 3540 is nothing [img]/ubbthreads/images/graemlins/wink.gif[/img]
Figure 300 RUM w/180 would be about the same as 300 WBY w/180 @ 3200 which was fine. [img]/ubbthreads/images/graemlins/smirk.gif[/img]
ALso recommend you hang around there as long as possible. But if you go, I'm behind you all the way. Did my thing years ago. Good luck [img]/ubbthreads/images/graemlins/smile.gif[/img]
