I used 'pew-pew' to avoid any P.C. drama. I think pew-pew became popular in the gun community when YouTube began censoring videos with firearms. If that isn't a problem here, hallelujah!. Fifty years ago I got my first air rifle, a Daisy bb gun, then a .177 Crossman pump, followed by a Benjamin .22 air rifle. A couple years ago I picked up a Gamo Swarm Whisper that has been a lot of fun, but cocking the rifle more than a few times plays hell with my arthritis, hence the move to PCP.
Yeah, 'savings' might be a misnomer. Between the rifle, the suppressor, the tank, the compressor, the scope, etc., I could have added another cartridge rifle or maybe a couple of cases of ammo. I agree the real advantage is trigger time. I can practice every day and, because it is so quiet, not bother a soul.
P.S. - Thank you all for the warm welcome!
