Well I bulk filled my first time today, picked up a 20oz tank last night and a local hardware does CO2 fills (paintball). It is near 80 outside today, rare for upstate NY this time of year.
Man this gun is a bit loud. Louder than my Crosman Sierra Pro springer, when its not dieseling lol. In fact, I almost think its louder than shooting .22lr Remington Cbee's
A heck of a lot cheaper, though. And more accurate
