I've got a Sako 75 with a E.R. Shaw barrel chambered in Remington 7mm ultra mag. Gun does not group to my liking shooting the factory 175 grain A frames. The only other offering in factory ammo is a 140grain, which I believe would be too small for my upcoming elk hunt this fall. At $45/box and poor performace a friend with reloading equipment is going to help me out. I'm having trouble finding data for this round would like any help out there. Overall I'm not happy with this chambering for the non-reloader. I made a mistake having it rechamber from 7mmSTW to it's current ultra-mag. Being a novice I wanted to lighten up the gun a bit and went for a lighter fluted barrel, and while I was at it I would have it chambered for this hot new cartridge from Remington. Well the cartridge is not selling from what I can tell and here I sit. Kind of dug my own grave I guess. Any help would be appreciated. I'm am planning on loading up some Barnes triple shoch x bullets with a recommended powder. What do you think of the bullet and grain weight for elk? Thanks
