Just got back from the range, here's what Iv'e found out so far. Seems to worse if you max out the magazine, that is put all 5 in a 5 rounder, 10 in 10 rounder.......

Most of the pointy nose rounds, think V-max, feed most of the time without incident. Flatnose and some hollow points are different matter.
However, only loading 5 rounds in a 10 round mag, and then pushing down on the rim of the last round several times, working the nose up in the air seems to help, at least it gets things started in the right direction.

Once I settle on a specific round, I'll probaly try bending the feed lips some and see if that helps.

I'll keep checking bck periodically.

Good luck.
