I believe that Rocky Mountain Cartridge Co. still makes cases for percussion-type Maynard shotguns. You may have to provide a chamber casting so they will have the dimensions for a perfect fit. Some years ago, they made me up 10 cases for a M-1873 .64 cal. shot barrel.

Will,

Go to the For Sale/Trade section, click on "Maynard 1873 cartridge conversion rings", and read reply #3 and reply #9 both by Green Frog.

You might send him a PM.

BP,
Just for clarification on this thread...M-1873 Maynards were not, technically, "percussion" cartridges. Those cases required the wide, thick rim and a primer seated in the case. The Maynard percussion shotguns and rifles required cases with the thin rim - slightly thinner than 1882-type cartridges - and were drilled with a tiny hole for ignition from an external percussion cap.

I only mentioned RMCCo making some M-1873-type cases for me to illustrate that they make many more items than what you see on their "Short List". They even state so on their website.

Will,
I wonder about consistent and reliable ignition with a long or deep flash hole in the base of a modified case....? It would probably work, but I wish I knew more about percussion Maynards.

No clarification needed.
Will's initial post sounded like he was searching for options to try to see what might work. 
Don't know what equipment Will has available, but for those of us who have a lathe etc, we can experiment with some easy minor modifications to existing low cost products to see if the idea will work out instead of spending a large chunk of change to find out it won't or is too much trouble.
And some of us love to experiment just because we can.

So, Will - H that was in July and i am curious now as to how everything worked out or didn't work out.
If you are able to give an update telling about what worked best for you, that may save "having to re-invent" the wheel.

I have the identical situation as you mentioned, i.e., a Maynard 1965 Second Model percussion breech piece with a .64 caliber shot barrel that I plan to take to the hunt field this year with black powder loading.

Thanks in advance for your guidance on getting me shooting.

C.M.M.

Froggie --  Have you ever tried using a modern made high brass, plastic hull that has been fired and then trimmed back in length using an Exacto knife?  The spent primed would then, either be removed entirely, or the spent primer left in the pocket, but drilled through with a small diameter drill bit?

In theory, that just may work satisfactorily, but for authenticity, its out the window.  When I'm out in the field by myself looking for multiple rabbit specimens, authenticity may be relegated to a position of subordinated importance; and a good rabbit stew (carrots, potatoes, and onions) in the cast iron covered 12 Quart being of utmost importance.
