I am in need of some help. Here in Maine you can only hunt with no more than five cartridges or shells I your firearm. I only have the 10 round factory mag that came with the rifle. Funds are super tight right now and can't afford to spend $40 on the four round magazine. My question is, is it possible to put a limiter/plug in the mag to make it only take four rounds? Would six empty rounds do the trick? I dont want to screw up the feeding.
