!!!!! I let ONE pellet loose out of her and the pressure gauge dropped 50-psi???? Is that "Normal"???? The guy I bought it from says it's set at the "Factory Settings". Sounds pretty quiet and I'm thinking of getting the shroud extension with the 2 additional baffles anyway - (what do you guys think of that addition?). I already have a scuba tank and a HILL handpump that I will need adapters for if anyone has something they want to part with 
This whole tuning thing has me a bit spooked too (but, I hear my Chrony will be a HUGE help).
