Bore sizes

Autumn Daze · 10-26-2014, 08:30 AM

Gent's, In the interest of gaining a bit more knowledge on the stamps found on Parker Bros. shotguns. Could those of you having 12 gauge guns(for now) with the + stamp on your barrels measure the bore sizes? Please report your results here. I am interested in bore size not choke constriction. Thanks!

this would be interesting survey,

but I wonder how many members have bore and or wall thickness tools. it might take a while to get these results.

Maybe someone could announce they will have a tool with them at the various shoots, and those with the barrels so marked could bring them.

Or -- Dave could organize a group purchase with one of the makers

I will go through my pile of junk and used barrels. I should be able to find quite a bit in there that have the + stamp on them.

My 1903 VH has .731 both barrels.

Eldon,
I just measured a 1 1/2 frame 1900 set WITHOUT +s that are .732 and .733. They have never been honed!!!
