BigCountry, I have loaded many 30-30 rounds and the best I have found to shoot in my Marlin 336 with the micro grove barrel is Hornady 170gr. flat points, IMR 3031 28.0gr. forget off hand on the primers (i'll get back on that and the C.O.L.) all cases are F.L. sized andtrimmed to max length. That load in my gunwill constantly put 3 shot groups in a 1" orange dot if I do my part.
