Re: 12-bore 2.5" fully rifled 10lb 2oz

Dear Sir,
The chamber diameter is approximately .815 of an inch, was nitro proofed in 2006 at 18.5 =.729 of an inch. We think that it would have been made for paper cases or thick brass, not thin brass. The twist rate is ¼” over the 26” barrel length. The rifling has 10 lands and we think is early Henry’s.
I hope this is all ok.
Best regards,
John.
I have a photo of the proof marks, how do I post photos?
Thanks again
Ben
