I just put new bottom metal in a Remmy 700 HS precision stock. I used my old screws when I put them in it tightens up fines but its like there are only a couple of threads catching. Is this normal? I just have to turn the wrench twice and there tightened up. Everything seems secure, I was just checking. They torque down right. Just worried about how many threads were catching. Are there supposed to be longer screws to use?
