Hey Sam. Im kinda partial to my 22 Disco. 8) You have a point about economy 177 pellets (very locally available also) only thing is,, the Disco is kinda powerfull for 8 gr. pellets :o there goes the locally available ones :0 I recently had a chance to shoot "J",s 177 Disco. nice,, shootin 10.5 gr. cp.,s. The 22 is a little more eficient (power wise). (more ft. lbs.) I did like J,s 177 though. Ya may want to shoot a PM to melloroadman (Marvin) or J (300n),, they both have 177 versions. Have fun either way,, Tim.
