Hey guys, before this goes any further, heating brass to 350F is not annealling it! It has to be heated to a dull red and quenched in water, and then only the case mouth, not the entire case!!!!!!!!! Before anybody goes off and hurts themselves, at least read the archived thread on brass annealling under the Darksiders Forum. If I wasn't at work I could find a good link for this but don't have time now.
