Thanks, Dan. That clears some things up. But I have often found "why doesn't my rifle shoot" threads to be something like chasing invisible rats down an endless hole.
All too often there's something really simple wrong with the rifle--though not always obvious. Earlier I mentioned a question from a member on a good load for 165's from a .30-06. I gave him my standard answer, around 58 grains of H4350, but it didn't shoot, even after he changed scopes. Six months later he contacted me, and it turned out he'd tried two brand-new scopes. Both were bad. With an old proven scope the rifle shot under an inch.
Another time went through a bunch of stuff with a question about a custom rifle that didn't shoot. After quite a few posts, from the OP and me and others, it turned out he hadn't tightened the scope bases down.
