[QUOTE="DTubb, post: 2842453, member: 8105"] 5/35 SMC 2004 Elliptical shoulder on a 20 cal bullet on a 6BR case with a 1.5” case. Bullet diameter in relation to Cartidge base diameter approaches 2.5 to 1. So based on that a 1.75” case with a .585 diameter head shooting a 6mm bullet would be the next step up. Needs a case full of slower burn rate powder. By Smalley sent me a 6mm elliptical shoulder reamer using 6XC case with a .284 case diameter held short. Didn’t see enough velocity increase to warrant any further experimentation. SMC= Bryan Smalley & Chuck Mcpherson [/QUOTE]
