Been shooting the SSTs for a long time in 270 and more recently 7mm remington. Incredibly accurate for factory ammo in all rifles I've shot through them. Always had great success on deer and antelope with them but was hesitant to try them for elk with my 7mm, but did so anyways because there so damn accurate. 154 sst at 3050 fps. Shot my bull at hundred yards this year with it and it did a great job. First shot was all heart and he was on wobbly legs, second shot I put through the shoulder and it crushed the scapula and anchored him. Didn't recover the bullet as I did gutless on him and expect that it fragmented every where which is fine by me. I think a lot of guys will lose game and automatically blame the bullet broadhead used when it could of been any number of factors. A great example is when an animal is lost with an expandable broadhead everyone will blame the broadhead, but when an animal is lost with a fixed broadhead every one will say it was shot placement. Same rings true for bullets IMO.
