I have an A-Bolt in .300 Winchester Magnum (not the short model). I have owned it since 1996 (Bought it brand new). I have never fired a round of factory through it, but I have fired 180 grain Hornady's, 190 grain Hornady's, 180 grain partitions, 180 grain Scirocco's, 180 grain accubonds and 200 grain Accubonds down the barrel and none have groupedabove 2", with most in the 1.5" range and a few loads thatconsistently shoot under an inch. I know I am lucky, but it has been a sweet gun.
