28 gauge pinfire double rifle - 07/18/19 10:35 AM

Good morning. I have a nice, cased Williams and Powell double rifle in 28 gauge pinfire. It will shoot an approx. .587" projectile. I do not know if it was made for a ball or conical bullet. The chamber fits a 28 gauge pinfire [smaller than a 28 gauge centerfire} paper shotgun shell perfectly if the case is slightly less than 2 1/2" long. The chamber is cut for a rimmed case. Other than that, I have no information on what cartridges should look like or how they should be loaded . I would date the gun around 1870. Twist is 1/36".

In a recent Holt's auction there were two cased double pinfire rifles, listed as 28 gauge. Neither contained any ammunition, so no hints from there as to the makeup of the 28 gauge pinfire rifle cartridge.

Does anyone have any information on this cartridge, or even a catalog cut from an early catalog of cartridges ? Thanks for any thoughts. Daryl

skeettx, Mr. Newcomer certainly has a wonderful group of cartridges, but he doesn't seem to have any pinfire rifle cartridges in 28 gauge available. Thanks for the lead, Daryl

I think you will be rolling your own in order to get this one up and running. I would start by slugging the bore and doing a chamber cast. Most likely designed as a bullet gun but it may stabilize rb as well. Try Jeff Tanner in the UK for ball molds, he is fast and very reasonable. Best of luck with it,

At one in 36 inches for a .58 caliber bore, this rifle was almost certainly designed for a bullet rather than a round ball. You might try something that casts out at about 450 grains to start, although it's possible the original bullet could have been lighter if it were a hollow point. I have no idea what an appropriate powder charge might be, but you wouldn't go far wrong by starting with a powder charge of 55-60 grains of FFG powder and working up from there until the barrels shoot to the same point of aim.

Let us know how you make out.

Aaron, I have not seen this . Thank you so much. Is it possible you could get some dimensions of the case and bullet ?

I cannot clearly read the case head on my computer. Is it British ?

I also have a German cape gun that seems to take a similar pinfire rifle cartridge, but it has a slightly larger bore.

Steve have you heard that Mr Tanner has passed away?
I do believe that his son has taken over the operation.
