So I have built a 260 Rem with a Savage 110 action. I used a Pac-Nor barrel. It has a Bell&Carlson Duramaxx stock. I have got the barrel broken in and now, shooting groups, it will shoot bullets where the holes are touching but every few shots, it send one about 4 or 5 inches high. I couldn't figure out what causes it. The barrel is completely floated. Could the recoil lug be the cause of this? It is the factory lug and it doesn't look like it makes good flush contact near the top of the action.
