I discovered the problem I was having with the magazine. I would load up the rifle 5+1, by loading the chamber and ejecting the mag to load up the 5th round. By doing this, when I ejected the round in the chamber, if I pulled the bolt back slowly it would push the end of the next round down, and fail to feed, which was fixed by cycling the bolt quickly. I don't encounter any feeding problems unless I load it up 5+1, so I'll just do 4+1 from now on. Just for future reference, what is the number for Maryland, I couldn't find it anywhere?
