I have been reading a lot about the 6.5x47 and it seems like it has a lot going for it, but the biggest selling point I have seen is that the Lapua brass in 6.5x47 can take a lot of pressure. I have also read that you can resize 243 Lapua brass and make a 260 out of it. This should take away the advantage of the Lapua brass in 6.5x47, or at least make them equal from a brass standpoint. I have access to a reasonable Savage 110 (long action) and am I am considering something in 264 caliber (6.5) with a fast twist barrel setup for heavies. I'm having some trouble deciding on 6.5x47, 260, 260AI, and 6.5x284. Since the 110 is a long action I would be able to seat the heavies out as far as I want with no issues with the action or magazine. The overal goal would be a platform that could support heavy 6.5 bullets at a reasonable velocity and get good barrel life. (6.5x284 is out?) What do you guys recomend?
