This is pretty much uncharted territory for me. I'm a rifle hunter first, now getting into hand guns. In terms of accuracy, I would say definite sub-moa at 100, estatic with less than or around .5 MOA. My ranges would vary, from 50 to possible 250-300 yard shot. I want a cartridge that is not only accurate out to those distances, but still has a little knock down power. The 7 BR seems to be what I'm leaning towards. Recoil should not be too bad in a 15" Encore. The accuracy should be there, I know thats the case with the rifles. I don't know, I guess I'm just at a loss with how to guage how a cartridge will perform out of such a short barrel. I'm so used to hunting with plus 3000 ft/lbs energy cartridges. I think I'm just a little leary of if the 7 BR and Waters will be able to fill my criteria, in lieu of going for a bigger pistol cartridge (like a 280, 280 Imp, 284 ....). Thanks for the help.
