I have a Rem.700LH that I bought new to build a 7stw out of it, but my gunsmithtpld me to try it put first that it would probably shoot and boy was he right. It shot the first load I ever tried in it and it will pretty much eat anything you put in it.
The most accurate load it shoots is 68.5gr. of IMR4350 with a 225gr. Hornady SP- 3 shots made one ragged hole at 100yds. And will plant anything it hits and they other load is 74.5gr. of IMR4831 with a 200gr. Nosler BT and plants things also.
I do want to try the 185gr. ttsx to see if they shoot as well. This is a powerful performing, hard hitting rifle and I don't plan on touching it other than to hunt with it and don't see any need for anything bigger that this case unless you plan on shooting it a long way. The only thing it does that could be improved is the recoil, it will punch you pretty good with those 225gr. Loads.
