Re: New 7mm SAUM Questions.
And for the O.P., yes, you can stretch the effective distance of that rifle past 400 yards for big game. For example, if you can push the 168's to 2,900fps as someone mentioned, that would get you out further depending on your altitude. At 1,000ft, your could get to 650 effectively. At 5,000 ft, it gets you to 700 yards. I would be interested to know what load Daveinjax thinks can work past 1,000 yards though, maybe there is something else you should be looking towards...?
