[QUOTE="MontanaRifleman, post: 241500, member: 11717"] 3006savage, .595 BC for a 130 gr bullet is very good. I didn't check the Berger site. I went to the Nosler site, because they have data for th 280 AI and I had checked it before, so I also checked their bullets. The BC of the 6.5/130 is essentially the same as the .284/140 in the AB's and the 150 BT is a little higher. According to their data (which I find consistant with my data in other cartridges) The 280 AI can push a 150 gr bullet at about 3100 fps out of a 24" barrel, which means it can probably push it at 3200 fps out of a 28" barrel. When comparing apples to apples, you get more BC, SD and vel out fo the 280 AI than the 6.5-06 AI. But... Berger doesn't offer a 150 gr VLD. So for grins I ran their 168 (BC .643) at an MV 0f 3050, which should easily be doable in the 280 (28" barrel) against the 6.5/130 at an MV of 3150. At 800 yds the external balistics are very close with the 280AI/168 surpassing the 6.5 down range. Terminal ballistics wouldn't be much of a comarison, with the 168 bullet having significantly greater mass, frontal, SD, momentum, and KE. Having said that, I think the 6.5 AI is capable of taking a large buck at 800 yds, but the AI can probably do it a little better and farther. Your other reasons for you pick are good ones, and it should get the job done with a little less kick. Good shooting. [/QUOTE]
