Race,
The .284 150's would only get within.037 of the lands and still maintain a caliber's worth of bearing. If I remember right I've run the oal out to 3.395. The 168s will reach the lands but they seem to like a "little" freebore. I'm going to try .05,.06 and.07 next time out. I'm getting 1" groups with several loads but mostly 2 in and 1 out so I'm hoping to suck the other one in. The two together are almost always touching.
