Stuart, I haven't torn down the pistol yet... just did a lock tune. Soon, though. I'll get some pics.Bill, I have made a valve for MSP, and started a fixture to install it properly... but time is short here, atm. It'll happen... Guys, the 400 is built like a truck. I think it was planned as a far more powerful gun than it is. It will be fun to mod... but if the barrel in mine is any indication, they will need a new one. It's, frankly, junk.The chamber is cut with something too large and with no taper. It would be OK if it wasn't cut way too deep (CPUM shown, dropped in)... and if the rifling wasn't indistinct. My chamber reamer can't help this one. I'm thinking a good 12" might be perfect for this project.
Sincerely wish this site had a subscribed threads feature So no harum scarum wierdness in there. Pretty stock looking stuff all round. Hm an LW 177, 22 and 25 trifecta barrel set might be fun.If you could get 400 fps or better out of a 25 on that it would make a wicked little pest control solution.
