I will check the scope, and scope mounts. As for the barrel being tight, Im not really certain how to do that. Is it something I can check at home? Also, that was from a leadsled rest, and though the trigger is terrible - I usually use very crisp triggers at around 1.5 to 2 pounds - I see no reason why my groups would be so large. Actually, I have looked down the bore, and it looks okay, though I didn't look through a borescope, but other than something being loose, I see no way that a group could be of that size. As for ammo, can you guys provide ammo suggestions for cheap, but good, ammo. All that I know when it comes to ammo, are the top brands, Remington, Winchester, Federal, Hornady, etc. I have no clue of what is good in the overseas ammo - I know I have been told stuff like, no steel cases, someone else even mentioned steel bullets with a very thin coating of copper, and that was pretty much it.
I plan to contact DPMS in the morning, and I am certain they will make it right, but the hassle of it all is just aggravating, so I plan to try whatever you guys mention as well as the scope possibility, then I give up.
Thanks for everyone's advice.
