how much velocity from a 18 inch barrel in 22 cal on a stock 1322? how much does aflat top piston add? my goal is 500 to 530 fps with a 13 grain pelllet. thanks.
For the money get a QB78, do some very simple mods and have a gun that will smoke a 13xxgun. I have built 3 13xx guns and they were nice but not evan close to a QB. So many options to do for little or no money,and if you have the funds the sky is the limit. Just my opinion as I still have 2 13xx guns. Wolfer
