Just snagged a new rifle. Stainless M70 Classic in 270 WSM. It was a screaming bargain with a Zeiss 3-12x56 MC scope sitting on it and has been Mag-na-ported.
I've already got a seldom-used Rem 700 BDL AS in 300 Wby in the safe. Curious, I did some comparisons between the two via Federal's ballistic comparison with the 300 shooting a 180gr and and the 270 shooting a 150 grain Nosler Partition bullet.
Almost identical performance. The 300 is doing it with the a 30 grain heavier bullet, so its obviously got more energy - but otherwise the graphs almost overlap completely.
So what situations would call for the 300 WBY that the .270 WSM couldn't handle? In my Michigan world of whitetails, I'd have a hard time 'needing' both. But maybe out west on Elk or on Moose or some dangerous game the 300 is the only thing that could do the job?
