I suggest you use cerrosafe to figure out what you�ve got ( I Did that with my .25-25 Stevens, it was fairly easy and inexpensive)
Agree with Marks21, out of proportion , it�s not 30-30 Ackley Imp, could it be 32 Special ( thought that was 30-30 necked up to 32 cal bullet)
Looking like a fun project,stick with it, I know you have grits in West Virginia.
By the way, thanks to this thread, I had a bit of a breakthroughwith my 2525 Stevens and my Hollenbeck drilling , I had the same failure to fire problem as mentioned earlier and thought my spring was messed up or my hammer not hitting hard enough, as advised,I jammed my primers as far up into the case as I could and ,lo and behold, with six test firing�s, four fired with the first hit with thehammer and the other two with the second hit. I�m in business now, I�m going to load the reduced load IMR 4227 with toilet paper and grits and have a blast !!
If I get a decent grouping I�ll share it and then I�ll eat some grits, I wonder if anybody looked up Roy Blount, Jr: �song to grits�as I suggested, it explains a lot

Hmmmm, well it is definitely not bored to .35-30 (a .357 bullet is a good bit wider than the case mouth).

Still haven't made it to town for a caliper battery lol.

I think .32 Winchester Special might be a good guess. I am still pretty dubious about that ring on the brass, though.

I guess I will see about fixing the left shotgun firing pin myself. Haven't taken it apart yet, but depending on what the right-hand one looks like maybe I can use it for measurements to turn a new one for the left barrel. Then I'll leave the chamber casting and any potential reaming for a real gunsmith...

Mr.Polecat,
Leave any reaming to a gunsmith( I recommend no reaming),but you should be able to make a chamber cast yourself. A .308" bullet should drop easily in a fired 30-30 case, if it won't, something is wrong. The old 30-30 chambers are usually pretty generous anyway. Slug the bore, a 30-30 will be around .308", a 32 Win.Spec. .321-.322".

I think the suggestion of a good side-by-side gunSmith is a good one( I bet when the gun is clean inside the action, other than maybe replacing the small spring that retracts the shot gun firing pin, that everything will work fine, and I think you�ve heard our suggestions about making a cast of the chamber and bore It�s easy,and will give you your answers
good luck in the end you�ll be glad you have a Hollenbeck drilling !

Given that there is a fireformed case available, I submit that slugging the bore would be more informative.

Weeeelp...

The fired case mouth ID measures ~.315-320
The fired case mouth OD measures ~.345-350

The bore at the muzzle measures ~.305. The caliper I used is only accurate to about 0.005, so I assume that's a pretty solid bet on the bore still being .308. If I measured it accurately, which is kinda questionable IMO.

Hmmmm. The OD of the fired case neck is pretty close to what .32 WS ought to be. I find it to be extremely difficult to measure bores and chokes accurately with a caliper, so I reckon I need to dig up some buckshot and slug it like you said.

You are right that it is hard to measure small IDs with calipers, because of the curvature and need to hit dead center. I am usually .001-.003" off, when compared to using small hole gauge and mic. A slug can be hard too, if the barrel has uneven number of grooves.
