I'm gonna flame the Dart feller. Ignorant to say "use a 150 grainer" thout sayin' use a good one. Also, thet crap 'bout hittin' the "one lil' spot" is a sure sign of a greenhorn. Huntin' ain't bench shootin'. Take enuff bullet. First time you find a wounded cow hoppin' round on three legs an' bleedin' thru her nose you'll know what I mean. A 150 from a 270 is marginal, but ok if its the right bullet and the right rifleman. A 150 from a '06 has less sexual density an' is apt to blow up on muscle an' bone. Stick with the 180. An' Dart needs to retire from givin' advice.
