[QUOTE="bearcat2, post: 2025647, member: 18832"] I would imagine (without doing all the engineering and geometric math, just a WAG) that a 170 gr. .277 diameter bullet built by Berger (insert your favorite long range bullet here) would have a better BC than a 170 gr. .284 diameter bullet built by Berger. As long as it is designed for a gun with enough throat/freebore and a long enough magazine to seat it out. That is a limiting factor from the rifle end, custom makers can alleviate that, you could have a regular old 270 Win custom bored with a longer throat and built on a longer action with a full length Magnum magazine, but the big bullet makers aren't going to make too many bullets for a theoritical future custom market. If somebody designs a factory rifle capable of shooting such long range bullets though, probably in conjuction with one or more bullet makers to make some factory loads, the others will jump on the bandwagon because there is profit in it. This is what Hornady did (although somewhat in the reverse, since they are a bullet maker who partnered with rifle manufacturers) to create the 6.5 Creedmoor. Now there are a ton of high BC heavy .264 diameter bullets out there for me to choose from to shoot out of my 260 (which has a fast enough twist to shoot them, unlike the original 260s that Remington screwed the pooch on) [/QUOTE]
