Fortunetly this rifle has liked bullets from 58gr-80grs so far. What I'm looking for is terminal performance with the 70gr and up. Looks like other people have had excellent results with 70-95gr bullets and of course the 55-58gr. What I'll end up doing is try the 80gr BTs I have loaded up and also try the Sierras and Hornadys once they're available in my area. I'll also have my loads chrono'ed to confirm the velocities. Thanks to everyone for their imput.
