I can help with the magazine feeding issue. I ran into the same problem with some of my mags. Bottom line....the opening isn't wide enough and the follower spring isn't strong enough to push the last round through the top when no other cartridges are putting pressure on the spring.
Too tight....
Just right....
Take a Dremel and open the lips a bit. The picture above shows how much I remove. I don't think a little excess matters either.
