12 ga zip gun velocity?

sixgunnin · November 28, 2017, 04:28 PM

How much velocity drop is there between an actual 12 ga barrel and a 3/4 inch pipe?

Beings there is no chamber the wad is going to be pretty loose in a 3/4 inch pipe. Anyone done any velocity tests?

I doubt anyone who has a 12 ga. zip gun, doesn't have a chronograph......

Just wondering if its worth building one. Maybe no one has one that can legally have real firearms?
