I hope this is the right section where to post about air rifles.
I recently bought a Gamo CTX Royal. At my unexperienced eyes seems an ok rifle for practice (target shooting at 10-20 meters). I tried it today and was a bit surprised by its power and loud shot.
My first question is: i have shot just a few shots with this. After each of them i saw thin smoke emerging from the muzzle. Is it normal? Consider that it was quite cold (about 0°C, -32F) and that it was probably the first time the rifle was shot since coming out of the factory. I read not to use any oils inside the barrel to avoid damage so what may be causing the smoke?
