I have a factory .243 blue barrel that will print the first shot about 3 inches above the group, now this is out of a cold barrel and doesn't matter if it's clean or not, and is very repeatable. Once the barrel is warm it will shoot a decent 1 1/2" group. I have floated the forend by sanding it down on the sides till I have good clearence, I have put in an oversize hinge pin and the action is stiff to close, and I don't think it is a scope or ring and base problem because once the barrel warms up I'm fine. It is that first shot out of a cold barrel that is the problem. I am shooting factory ammo, but I don't think thats it either. Anybody out their experience this, and if so what to do?
Thanks, Ben B.
