My Storm lake barrel in 9mm run clean with the Lee 120gr TC at about 1100 FPS. It takes that speed to run minor class. I use a very slow powder.
In 40 it does shoot very clean but I only load a 175gr TC to about 800 fps. I call it my 40 super wimpy load. Recoil is very low at slow speeds and follow-up shoots are fast.
Nice thing about a Glock 22 is that I have two Strom lake barrels for it, one in 9mm and the other in 40.
P.S.my factory 40 barrels leads very fast yet in the Glock 21SF the factory barrel shots clean.
