Browning A bolt 300WSM here, 180gr. Nosler Ballistic Silvertips with 69gr. H4831SC. I don't have a chronometer but figure ~2900fps as a guess. Shoots extremely accurately. Not that I had a chance this year to test that out on an actual elk though...
For antelope, 150gr. BST do nicely.
I also have a bedded thumbhole stocked M77 MkII .308 with trigger work and a 4.5x14 Burris BallisticPlex scope. Shoots dimes. Just a bit more drop than the 300. Less punishing (not nearly as light as it was with the fugly plastic stock). Lately it seems I've been letting other (new) hunters use it... something wrong with this picture.
I am having a lot of fun with a Savage .243 too, just need to work out loads for it. It likes Federal factory 100gr. and hates Remington. Quite a difference really. Too light for elk though. Dandy for deer and lopes.
