Hello everyone!

I dipped into the 2011 realm and got a Cos 21 chambered in 10mm and it would not fire more than 6 rounds continuously...

I had 13 pre-mature slide lock backs with rounds still in magazine....

27 inertia feeds
8 stove pipes
34 cases that look like an alligator chewed them



added extractor tension, changes magazines, used full power 10mm, watered down 10mm, hollow points and various grain weight.... HELP

If you can get photos of the barrel ramp, it would be helpful.
