Jag mag I totally agree with you. There is a myth that a large fountal bullet will plow thru brush better then a high velocity round will .Why?The only reason a rifle was termed brush gun was its ease of carrying it thru the brush. ei win mod 94. So back to the subject at hand.You are right that you cant shoot at short range calibur at long range but I have and have seen a .270 win at 10 yards not do its job ( make a wound channel and or mushroom out ) and that was with factory ammo 130 grain sp. So I have watched my 30-30 and my 45/70 at close range kill more effective then a .270 or a 30-06. And I know certain bullets will do better but we are talking about the average here . I will take my 45/70 any day out to 100 yards and then my .270wsm or .300 win mag after that.
