Numrich underhammer pistol
Jim in Wisconsin:
I just bought an old Numrich underhammer pistol. I thought it was 36 caliber, but the bore diameter is actually .352 with 8 grooves. I have some .350 Hornady balls and managed to try one with a patch, but that is way too tight. I think a good size would be about .335 to .340, but that doesn't seem to be a common size at all.
I have a lathe and made a die and punch to size some .350's down to .334, just to try that. They end up looking more like a bullet than a ball and didn't seem to be very accurate, like all over the paper at 20 yards or so.
I see Track of the Wolf has cast balls of .340, I should order some of them. Any other ideas?
I don't suppose anyone else has one of these oddball pistols.
Thanks

Jim, can you post a picture? Not sure if I've ever seen one.
Jim in Wisconsin:
I'm not very good with this computer stuff and don't know how to put pictures on here, but if you search for Numrich or Hopkins and Allen Boot Pistol you'll see them.

There's a pic in this thread: https://www.muzzleloadingforum.com/threads/underhammer-pistol.125702/
FWIW:
* H&A underhammers have undersize bores, compared to other maker's - my .36 H&A Heritage took patched .340" balls, which I got from www.trackofthewolf.com
(I would strongly advise obtaining an extra nipple specific for the H&A, and a nipple wrench, from TOTW @ the same time)
(Other brand .36's take a .350" ball)
Alternatively, .330" OO buckshot or a Hornady .314" SWC boolit can be used, both with patches.
* I used (and still do) about 15gr (+/-) FFFg for my H&A and T/C .36's - any brand of Holy Black you can get your paws on will do nicely.
