Well had to get out and try a couple different loads, as everything up to now has been the berger 205. Shot 180 SGK, 200 Eldx and Nosler 180 BT. The dang BT went in a group just under 3/4" and held decent on steel at 400 and 600. (No load development, just loaded up 10 at reasonable charge and sent them. (Same for all of the above.) Different shooter. Gun was funky with all (not good groups) and then the BTs went two in the same hole and 3rd just a smidge out. Go figure.
180 BT on Elk? Just kidding - that's a whole 'nother can of worms.
