Sounds about like my Hawkeye 30-06, SuperstitionCoues. Mine didn't like the Fusion 165s from Federal. I got about 3" out of them. At first I was afraid it was the rifle. (I mean, c'mon, it couldn't be the shooter!!!) Anyway, I switched over to plain old 150 grain PowerPoints. I shot the groups a little different than most. I fired two shots, then waited. Two shots then waited. Etc... (My goal in this type of shooting is to simulate the initial hunting shot and then a relatively quick follow up. I don't know if it really helps working from the bench, but that's my story and I'm sticking to it.) After 10 shots in about 20 minutes, I ended up with 10 holes in 1.65" I think I've found my deer load. I'll play with the reloads for bigger and smaller game though.
