I'm agreeing with everyone else, nice cannon (and Welcome to Spufiles , just times one but it'll do ). Take their advice and add the fan and barrel length.

Also, does cutting the barrel like that actually do anything for the performance? I've seen it done before but never tried it to see if there was any improvements.

Im not going to make it 60" ....id have no way to transport it, lol. Ill add another foot or 2 and see how it goes.

What do you mean "cutting the barrel like that"?

well i added 2ft to the barrel, a ball valve and properly sealed everything 100% and now im up to 225yds. Verified with my portable GPS.

barrel made a huge difference. Next up is mapp gas. followed by a total redesign for an over under gun with about double the chamber size i have now. Hoping to pull 300+yds.
