Issues with two different guns.

The first issue I'm having is with an Noveske rifle. Before I get to the issue, both upper and lower are Noveske that I bought separately and the lower I had to assemble myself. The problem I'm having is with the bolt closed, I can't get a loaded magazine to latch into the receiver. Now if I lock the bolt back, the mag will lock into the receiver no problem. The magazines are PMags. Is it something I've done while installing LPK?

Second issue. I bought a new 4" barrel from EFK for my XD9. At about 5 to 7 yards I'm getting key holing. It happens with every 3 to 4 rounds. The ammo I was shooting was PMC Bronze 9mm Luger 115 grain. The other mod is a polished guide rod and a Wolff reduced power 18# recoil spring from an 1911 .45. From the factory it had a dual recoil spring set up. According to the instruction with the spring it says to use reduced power loads. Could the ammo I was shooting with that recoil spring cause keyholing or was the 115 grn. ammo I was using incorrect for the rifling?

Are you 100% sure it's keyholing?

If you bump the ar mag firmly with the bolt closed, it won't latch?

Count your rounds in the mag. I had that issue with my AR and had 1 round more than its supposed to hold

Not completely, I was just having some round holes and some that were rectangular in shape. Also, not sure if it made a difference, but my target was one of about 3 others that were still stapled. Could multiple sheets (targets) of paper cause the bullet to appear as a Key hole?

No sir. I've given it a couple good hits and nothing, locked the bolt back and the mag locked into place easy.

That's what I didn't do was count my rounds. Perhaps I just topped out the mag thinking it was at 30. I'll do a round count next time and see if that's the problem.
