I seem to be having a problem on both of my rifles. They are both in HS precision stocks. When tightened down should the box magazine have some play in it? Mine are very tight. One of the floor plates are flush behind the trigger guard, and about 8mm high in the front. I am having feeding problems in both, scratched brass, and scuffs on bullets. When they were in ADL stocks this did not happen just when I changed to hinge floor plate the problem occured. One rifle is brand new, the other about 100 rounds through. Need some help.
