I am wanting to build a new rifle 10lb or less that I can shoot comfortably without a brake. I have shot a 325WSM that was 8 lbs and a 300RUM that was 9.5 lbs --- both had too much recoil to shoot for extended times at the range. Intended game would be deer/elk out to 800 yds. What caliber should I consider assuming I do not want a belted cartridge. I was considering the 7WSM and 300WSM - any others out there I should look at?
