2700 fps would get me out to 1500 yards, which is where I want to be. I'll have to research the 338x375 Ruger as a possible alternative. I'm not stuck on one cartridge, but I definitely want it bigger than a 308 bullet which pushes me to the 338s. I've played with the small and fast bullets, and I'm wanting to start playing with something a little bigger...

Of three cartridges, any show better natural accuracy than the others out of short barrels?

Thanks,

Danny
