How many of you have converted a co2 gun over to pcp via a safepac? I've had a few 2240s, but I decided to toss one in the 2260 shorty I built. I had the maker cut the end down to 1/2" so it just looks like a fill cap on the end. I get about 14 shots at 525-550 fps with FTTs. It only has a 12" Prod barrel in there, so that's why the velocity is low. It stacks the 5.53mm FTTs at 20 yards so that's all I ask of it. Already smacked 2 starlings this morning with it.
I also had to tap the transfer port with an 8-32 set screw and drill that out to 3/32" to get a stable shot string. Otherwise it was in the 700s for a couple shots and then fell off like a rock.
I do have a discovery valve set I will eventually put in the gun to get more power and shots, but it's so quiet at 10 fpe that I might leave it. The trigger is stiff though, since the spring is a .045" wire and cranked to the max. Cocking is stiff too. That'd be corrected with the Disco valves. Only running such high pressure to get the shot count up.
