Ive seen lots of game shot with both...as well as the 308, and 30-06. Ive always liked the 7x57 not because it was more effective...but because it has the least amount of recoil of the whole bunch...and by a fair margin.
As far as effectiveness...they are all about the same imho
Hi Joe, for me I'd sooner use a Short Action 7-08 than the "tweener" 7x57.
As far as recoil, I've only found the 7x57 less recoil-wise with 140's and lighter, but not by a "fair margin." With 160's, I find it a bit sharper than a 308 with a 165, and about the same as 270 with a 150. Ditto the 7-08.
But all of them kick noticeably less than the 30-06.
As far as game effectiveness, I've used them all on bull elk and at normal ranges haven't seen a difference with any of them, including the 7-08. I just like the bigger 270 engine. It does more with heavies than the smaller 7-08/7x57 engine.
But the differences are likely immaterial in the real world. But I will say a mushroomed 270/150 Partition is a beautiful thing!
