I am looking for info for reloading brass 10 ga shells with round and conical bullets with black powder and smokelss equivlet.

What is the chamber length and bore diameter of your 10? How much does your 10 weigh? Generally 10 bores regulate with 5 to 8 drams black powder, could go a bit higher, and there are equivalent nitro loads. Can you share some photos of your double?

The gun is a Greener 10 ga rifled bore sxs,hammerless h/brk with 28 inch bbls,box-lock with 2 leaf express sights.I have not cheched the actuall bore dia yet,Ithink the chamber is about 2 1/4 inches as a 2 1/2 inch brass 10ga shell doesn't fit all the way in. the gun weight is approx 9 lbs.

The gun is fully rifled? The weight would suggest a round ball 5 or 6 dram load. What are the proof marks?

Both barells are rifled fully,there are very few proff marks but I can see Birmingham black powder proofs , each barell is stamped with a "R" thre is also the number 11 and some unreadable mark over a 12M,there is also the letter "T" beside the proof marks on the right barell,and they are marked WW Greener

My guess is round ball at groove diameter or a couple of thousandths over 2 5/8 case, 5 dram load. 8 dram conical 10 bore rifles weigh in at about 13lbs and Greener was not known for under building his guns. My first thought was a ball and shotgun as the weight is right but it is fully rifled.

I bought this gun a couple of weeks ago at auction , I thought It was a ball & shot gun, but it has full rifling,damascus barells and is,I think, pre 1900.I have sent an info request to Greener in England but I have not heard back yet. the gun is in such nice shape that once I have it gone over by my favorite smith I want to go out and shoot it. The serial # is 1402 but I have not been able to pin down a date of manufacture yet.It didn't come with any case or accessories , so I'm kind of fumbling in the dark with this.

I took a couple of pictures butI don't know how to post them, if you pm me a email address I will send them to you.

Sent pm with my address. Is the rifling shallow?

To me it looks normal but I don't know what it should be, but a guess would be 1/16 inch deep,and nice crisp edges on the lands. I checked my pm and yours didn't make it through.

Some of your photo files were in aspx and I was unable to get them to transfer.

So what do you think? Is this considered a light bore rifle for ball only? I have read that load info is stamped on th barell but I don't see anything like that.

No, load info is not always stamped on the barrels or flats. Wait and see what the ledger page says and get a chamber and bore cast. It may be and early Greener ball and shot meant to compete with Holland's paradox. That would have been made between 1886 and 1901. Or perhaps a light rifle.

Thank you for all your help.I sent the request to Greener 2wks ago,if Ido not hear anything by end of next week I will try to phone them.I didn't think that this gun was such an oddball, but that will make it more fun to get up and shooting.

Thanks again;
