[QUOTE="davkrat, post: 506592, member: 6452"] Berger does make 130, 140 and 150 gr. .277 VLD's but the BC are .452, .487, and .531 in the 7mm the lightest VLD is 140 gr with a BC of .510. The 7mm start at a BC close to where the .277 ends. The Nosler Etip in .277 is 130 gr with a BC of .459 lower than the .469 of the .308 150 gr. I use in my .308. I wish they would offer a 160-170gr. VLD with a BC up around .600 that would push the .270 quite a bit and I'd think a .270 WSM or Weatherby coulld really take advantage of a long heavy bullet. Unfortunately I don't think there's much market for that style bullet. If Nosler offered a heavy Etip with high BC that would be great too. Maybe I'll just make it simple and go with a .280 AI that would only require a barrel swap. That way my brother and I could still use similar components (bullets at least) in all our rifles. The 7mm Etip at 150 gr. has a BC of .498 but once again that is very similar to the .308 150gr I use. The 280 AI could certainly get more velocity than the .308 Win but not a huge difference.
