What are the most common bushings for the 30BR - I have seen .324,.325,.326? Which ones would be the best to start with? With a .330 chamber and a 10thou x2 neck thickness plus the 308 bullet diameter I get a .328 measurement leaving 2thou diff and wanting 3thou neck tension and 1thou for case spring back I would think the .324 bushing would be the best. Should I go with less neck tension? This is in a single feed bolt action. Any suggestions on where to start with neck tension for the best results is appreciated.
