I recently bought a browning a-bolt composite stalker in .30-06. If I fire 8 rounds one after the other at 100yards I get the following: First two make 1/2" group wherever you wantit. Next two shots drift about 3" left and make 1" group. The rest of the shots appear randomly, but remain within a 6" group. So the hotter the gun gets, the more randomly it shoots. Seems the first two shots on a cold barrelare all it can do 'reliably.'
I'm using Remington UMC 150gr full metal jackets, and Remington Express core-lokt in165gr. Results are the same with either ammo. I've hadseveral other people shoot therifle as well, with the same results. Clean barrel, oily barrel,or slightly dirty barrel doesn't seem to matter either....the first two shots always go where you want it, after that, who knows!
SOOOOO is this normal a-bolt behavior, or?!? Could the remington cartridges be too fast or slow for this rifle? What does everyone else use for ammo??
any info appreciated as always..
