600 problem solved!
Pellet loader had two loose set screws! Works like a champ with CPHP.
This thing needs a longer barrel and a shusher, damn is it loud.
Let us know if you get a longer barrel, and the results. I have a 24 inch .22 Crosman barrel I'm thinking of cutting, turning down, and splitting between 2 600 projects. Right now I'm thinking 1 8" (enough for a shusher on it) and a 15" from what's left.
Of course, loud is part of the fun with the 600
