Your barrel has been cryogenically tempered, so there won't be any "stringing" issues. Your factory ammo, the breeze, or somethnig else moved that last shot. As for your group size, there isn't a police sniper in the country that would hesitate to take a rifle shooting groups like that to a SWAT call out. The R1 was never intended to shoot ragged hole groups like a $5k benchrest system. If that group doesn't impress people, they don't understand the dynamics of shooting an out of the box, semi-automatic rifle with factory ammo. that group should have ANY shooter grinning ear to ear and trying not giggle!
