I am shooting a 300 WM in a Mod 70 with a controlled feed. Is there anyway to change to a 'push feed'? I am loading for single shot-since COL is too long for mag. I would like to elliminate need to insert the round into the mag. in order for the control feed to grasp the brass. When I do this, the tip of the bullet almost touches the loading ramp. If it is possible to switch to a pushfeed will this hurt accuracy?
