Hi All, I have a strange problem (maybe) with my new Gamo Recon Whisper rifle. The Crosman Competition pellets are a very loose fit and will fall out of the breach if I close the gun normally, I have to point it downward for them to stay. But they shoot fine, well, when I don't accidentally crush one on it's way out of the breach I have tried CPHP and they are a much tighter fit, some won't go in without a significant push, but when I look down the barrel after CPHP I see some kind of black/brownish smoke. It disappears if I blow into the breach - is this dieseling? I've shot maybe 100-150 pellets through the rifle and it's still doing it with CPHPThanks!
Ok, I have no idea what's happening, but the more I shoot this rifle the louder and harder to cock it gets! I am now getting mild ringing in my right ear after each shot indoors and it feels cocking effort is increasing... I am about 500 pellets into this rifle and it should be fully broken in by now...
