Over the weekend I had the chance to shoot a .400 double-barrel rifle thing...shot the 450/400 Nitro express rounds, and a .300 MAG. I'm hooked now - and think in addition to my M4, I'd like an honest good hunting rifle w/o breaking the bank. That .300 Mag was VERY appealing to me - the $2000 price tag for the rifle, however was not.

Any suggestions?
