Nice work Scott.
I'd like to see what numbers you get from it, and what it weighs out at.
As a rifle I was getting 120+ shots at 11.5fpe. Regulated volume was 170cc. Barrel length was 20". The regulated volume is now 80cc. And the barrel is now 14.3" long. I'm hoping to get 60 shots at 11.5fpe as a pistol. Weight is 6.5 lbs as shown, including scope, wheel, & mounts.
It'll be a while before I can do extensive testing.
Edit: Did some preliminary testing. I'm getting the shot count and fpe (60 shots at 11.2fpe) but the accuracy is not there yet.
