[QUOTE="Rhovee, post: 2071691, member: 101820"] .308 isn’t more efficient bore. I have a 7 saum that shoots a 184 Berger at 2900 with 64 grains of powder (H1000). To get similar speeds with a .308 bullet (215 Berger) I have to burn 2.5 grains more powder in wsm. A 300 saum couldn’t come close to matching BC and speed of 7 saum. [/QUOTE]
