I SLIGHTLY rounded the edge where the ramp transitions into the chamber and did more polishing of the chamber, and ramp.
Took it out and fired it yesterday with 200grain bullets without ANY malfunction.
I now have a stainless 6.02" Storm Lake barrel with ISMI Stainless Captured Guide Rod with a 22 pound spring and a much more supported chamber.
Pistol works great and ejects the brass slightly behind and to the right from 6-10 feet.
I'm very happy with this barrel.
