[QUOTE="1894C, post: 2071718, member: 114886"] Well that would make the 7mm overbore now wouldn’t it? The answer is yes. The 7mm bore is at least as efficient and I would argue more so than the 308. Your statement on comparing both a 7 and a 30 with a 184 grain bullet to make it an equal comparison could not be further from the truth. Compare equal bullet sectional density’s when going across bore diameters. Not weight. Do you realize what a 185 grain 30 cal BC is as compared to his 184 grain berger? .550 to .695 that is not even the same ball park. However his 184 berger vs a 215 berger the BC and sectional density are practically identical. So yes his comparison was perfect and your rebuttal missed the mark by a mile. [/QUOTE]
