I shot a 281 over 6 cards last night but the BEST thing is I got a p.b. fill of 266g (short cyl.). Now 274!

Karbon Fillin King.
p.s. I know you use that (very expensive) FWB grease on the threads of FWB air cylinders but can you use (cheaper) say Moly grease on the threads of CO2 cylinder threads????
