Palmers brass barrel bore size

[danny1911]

Does anybody know the bore size of a palmers or give me a link to a chart i remember seeing one searched and can't find one

From what I can see there're 3 different sizes: .685, .690 and an "elliptical shape that can fire any size paint." If you can shoot most paint and it seems pretty circular to you then I would assume that you have the .690.

honestly, it doesnt REALLY matter. Ive contacted PPS about this. They have eleptical honing meaning that the bore varies inside the barrel. It gets larger, smaller, larger. this allows there to be a proper barrel to paint match at SOME POINT down the inside of the barrel. This is also why a PPS brass will shoot pretty much ANY size/type of paint as well as any other without needing to switch inserts, backs or barrels.
