Early 10 bores were .790" approximately.

I had a 1870's lifter 2 frame with .802 bores with .050 wall so i would say factory dia.??? my 1889 2 frame EH has .783 and my 3 frame 1890 EH has .780 dia bores. i would say you are very close to wright size on yours.

One of you 10ga. guys should gather information and plot it on a graph like Austin did for the 12ga. The oversize bores on the 12ga. ran till approximately the 60k range, then went down to the nominal .729 range. That would be an interesting study.

The 10 lifter on a 2 frame I just got is way over .792 (the highest my Skeets gauge will go where the gauge starts hitting the three inches of choke) and has barrels averaging .050 at the very thinnest spots. Where my gauge starts measuring to the end is .030 choke each so if I allow for the overbore I can't measure the overall constriction is pretty tight. 1878

Thanks for all of the replies so far. Would anyone hazard a guess as to whether or not the bore diameter would/might be based upon frame size. My lifter is on a # 3 frame, and it has the step from chamber to bore ( no forcing cone ). Sometime today I will measure the chamber diameter with my High Tech Tape and Dowel, and will post it later

Posted this on another thread. 1878 10ga 2 frame. Can still see reamer marks in the barrels, has CC on 90% of breach face and roll joint. Gun was shot very little, both bores measure .792 with .23 choke. Many early 10's were overbore by todays standard.

Robert, what does the rib inscription say for barrel steel? Your gun shows as PT (plain twist) in the stock book.

Yep, Plain Twist. Love the hand engraved rib.
