I've never shot a 300 wby, but my 340 kicks a lot. I'm just a little guy to, 150lbs 5'7", so that 44lbs is about 1/3 my wieght. I don't have a muzzle brake either, but have thaught of putting one on. the most shots in a row i have fired is 9. I get about an 1 1/4" groups at 100 yds. and have shot out to 350.
