what's military use got to do with it ?
i own 2 - 300 wsm's. my factory winchester (usta be)laminated classic, took a bull elk at 402 yards. i was running a 150 barnes tsx, and it blew right thru him, double lung !
this year, my lilja barreled one took 3 antelopes, 2 over 300 yards out.
very accurate, easy to load for, and lots of get up !
