I recently bought an 1885 10 bore from a seller who told me that it has 3" chambers according to his chamber gauge. I don't have a gauge, but an unfired 3.5" 10 bore brass shell leaves 1/4" protruding from the breech, suggesting that the chambers may in fact be 3.25". This test worked when I tried it on a 2.5" 12 bore: a 2.75" brass shell only goes in 2.5".
Is this a valid test of chamber length?

Doubtful. Just measure it. Roll a piece of paper and insert. Mark the place it stops and use ruler to see how deep the chamber is...Geo

No. It is not.
I like and use the machinist's scale method. Very repeatable with a little practice. George's method works too.

Thanks for the quick responses.
I have tried both those methods and can't get consistent results. I clearly don't know what I am doing but will try again.

Then I would need to buy more guns to justify it and I can't afford them!

Yeah? What are your eyes and/or fingers worth?
How about this? I have the chamber gauge set I pictured above, the 10 gauge brass is 0.82" or 21.2mm wide. Make yourself one out of some old metal sheet and see how far in it goes.

LGF, I think it is doubtful that your chamber is 3", I think the standard, at the time, was 2 7/8" or shorter. If it is 2 7/8", it would be pretty easy to mis-measure and think it is 3".I think Buffalo Arms( no connection) may have shells loaded for old guns. Mike

Then I would need to buy more guns to justify it and I can't afford them! No need to buy a chamber gauge for $45. Two doublegun friends here in town just come over to my house whenever they buy a new gun and use my Galazan gauge. Find a friend locally who has one and you can usually pick up a free beer and political advice in addition to getting the accurate measurement...Geo

I can see where owning a good gauge could become expensive...
