A reamer that is +.001" too large in diameter can jack things up pretty quickly, as in tight chambers and short throats.
Run that reamer like a bad boy until it gets smaller from wear and see what happens.
Am I missing something here? I can see how a longer reamer can make a shorter throat, but how does a reamer larger in diameter make a tighter chamber?
