I've started planning for a new rifle build, and will be sticking with a 7mm projectile. I own a 7 SAUM, and a 7 Rem Mag already, and want to be able to use the same suppressor between all three rifles. This rifle will be built specifically to shoot the 7mm 195 gr EOL Elite Hunter. I want it to be in the 3000 fps range, as well. I know what parts I want to use for the most part, but I don't know what cartridge to use. This rifle will be used for Elk and Deer hunting, as well as 1500+ yard target shooting. I'm wondering what the most efficient cartridge is going to be for this task? From what I can see, the 7mm Norma Mag (300 Norma Mag necked to 7mm) looks promising. But what say you guys?
