I'm trying to remember the name of a rifle(s) that had a rimfire firing pin and a percussion nipple.  The percussion nipple allowed a shooter to pierce a spent cartridge, reload it and fire it with a percussion cap.   
I thought it was a Ballard, but can't find any verification.

Thanks.

There is a fellow on YouTube that shoots one of these. Calls himself Nitwit. You got to see this and some other of his videos as well.

I've shot my 32 rf Brown Ballard with both rimfire and percussion caps.  They actually work quite well.  I saw a tool one time that was just a punch and base to put a hole in the original rimfire case.  That way, the original case, once fired, could be used again by filling with powder and a bullet.  Lots of fun to shoot that way.

Ballard rifles had numerous makers, and all except Marlin used the dual ignition system. Ball & Williams didn't use it when they began as those were RF only at first. But Merwin & Bray patented the RF/percussion system in Jan. 1864, and it was incorporated into the Ballard design. M&B owned Charles Ballard's patent, and had a number of different makers build the Ballard rifles...unsuccessfully for the most part.
Makers were Ball & Williams, Dwight Chapin & Co., R. Ball Co., Merrimack, Brown, and finally Marlin who was the only truly successful maker of Ballard rifles.

Joseph Merwin, a firearms designer and marketer, formed several partnerships, most notably with Edward Bray and brothers William and Milan Hulbert.  Together with the Hulberts he owned Hopkins & Allen.  And he invested in and/or influenced several other other gun manufacturers, including Evans, Meriden, Harrington & Richardson, Forehand & Wadsworth, and Iver Johnson.  However, neither Merwin nor any of his partnerships ever made any guns themselves; rather. they were jobbed out to already established makers.

Unfortunately, while at least one of Mrewin's designs, the "ugly duckling" Merwin& Hulbert revolvers made by Hopkins &Allen, were technically innovative and built to very high standards, most of Merwin's projects only drove him and his partners into debt.  Merwin died tragically in 1879.
