Try putting the front bag in different places on the forearm. Close to the action seems to work best, but not always. Shoot a 3 round group, and then pull the 4th round out of the chamber, like rocky says, it may be bent or otherwise chewed up when it got slammed it to the action. Are you shooting 3 or 5 round groups? Are there fliers,and is there a pattern? I have seen them shoot off one side of the clip, and throw double groups, which means it shoots one place when the round is loaded from the left side of the clip, and someplace else from the right side. Are the first 2 rounds closer to each other than the rest? Sometimes the first round with semi-autos is a flier, becaues the rifle has to load the round itself. As the gas chamber and barrel heat up they somtime throw fliers, try shooting 2 rounds, then let it cool completely before shooting the 3rd. IMR4350 is a good place to start with an `06. Try some sierra match kings, in 168-175 too. Semi`s are hard on brass to, i`ve had good luck switching to lapua brass, but it`s expensive, and you cry when you lose one, lol. Let us know how it goes.

I took it out over the holidays after loading up some 180 Nosler BT. with loads of AA3100-55, 56, 57, & 58 grains. 55 and 56 were bad 3" groups 57 and 58 were good but EXACTLY like you say 2 destinct groups, I shot 3 shots the 2 should have just went with 3 and saved ammo! I will try and post some pics of the groups the both had 3 shots with less than 1" but the 2 others out together I usumed this was from the barrel heating up. but after you saying that about the clip it makes me wish I would have read this first before I went back out so I could keep an eye on that. I reckon I should acept it I is shooting well enough to take a deer at 100 yards. And that was the only goal for this rifle. I just didnt acpect to have to shoot 180's in it.
Thanks for the tips and advise from all who pitched in.
