Thanks for the help. I'm not a treasure hunter, unless you call older guns purchased at gunshows treasure. I bought a Winchester 1897, in 16 gauge, that was built in 1912. When I measured the chamber I discovered that it had a short chamber, probably 2 9/16. I just put the shotgun in the safe, and then I came across some old(ish) Dominion ammo. I examined it and it sure looked like it was 2 9/16". I test fired the ammo and shotgun. Hulls were 2 9/16 when fired and the fit in the chamber was proper. I put together a short write-up and one of the details that had me puzzled was the N
o. I've shot and reloaded most of the shotgun gauges, as well as a few rifles and handguns. I've used older components, but never came across or noticed the N
o. So before sharing my write-up with other shooters, I wanted to confirm the N
o.
Information has been collaborated. Thanks.
In all my searching, this forum has the most information on ammunition headstamps, in all likelihood because that is all that you find. Identifying it and dating would be important.
Thanks for your time, TTFN.
PS:
The ammo I'm referring to, the rolled crip ammo is pre 1955, and the proper length for my shotgun.
