If the rim of the hollow is larger than the o.d. of the primer, AND, if your magazine is a fairly snug fit on the ammo, it should be all right. The center of the anvil is in the center of the primer cup so it should take a pretty direct hit to set it off. I''ve used some commercial hollow point 125 grain stuff in my 94 and 336, but most often only load one in the chamber and one in the mag. The few times I've loaded more than two I had no problems.
