I agree with BSA, but what you wanna do makes great sense as well. I like them all, even trying a 30-06 out a little these days.
A 338-06 or 35 Whelen really has some good stomp to it as well. Not sure you have HUGE gains, but it certainly will dig big holes. A 210 Partition at 2750 is a beast killer in my opinion.
I'm glad you brought up the 210 partition. That's what I was thinking as well. They are also on sale now at SPS. I NEED to get some for my 338WM....:
Good deal on .338 210gr. partitions
