C. D. Leet & Company Pinfire Cartridges
In our continuing saga of the relationship between pinfire cartridges and the United States, this post will take a look at C. D. Leet & Company.

Last post we talked about Christian Sharps and their problems with being able to fulfill their pinfire cartridge contract. Because of the delays, the Frankford Arsenal received permission on February 20, 1862 to buy 200,000 pinfire cartridges with the higher powder quantity “equal to those of Colts army revolvers” from a different manufacturer. So on February 28th, Captain Crispin contacted C. D. Leet to order 250,000 pinfire cartridges. This was actually the very first order, for any kind of cartridge, that C. D. Leet received from the Army.
C. D. Leet delivered the first 50,000 cartridges on April 14th and received a payment of $856.25 for them on April 30th. They deliver another 88,000 in the beginning of May and the rest of the first order on May 16th. On May 3rd, 200,000 more were ordered which were all delivered on June 17th. The final order of pinfire cartridges from any manufacturer was Dec 10, 1863 for 76,000 from C. D. Leet which were delivered on December 30th.
C. D. Leet was the only manufacturer who seemed to have had no quality issues with the cartridges they delivered. You will notice that the design of the cartridge is a little different than Christian Sharp’s version. Leet’s cartridge contains a lead plate at the base of the case rather than having the case itself be reinforced. The next manufacturer we will look at uses the same technique as well. This had to have been easier and more efficient than Sharp’s method and is probably why there were much less issues manufacturing them to an acceptable standard.
Their total tally of pinfire cartridges ordered and delivered comes to 526,000.


In addition to the pistol cartridges produced for use in the American Civil War, C. D. Leet also patented (#98,278) and produced the first paper shotshell with a metallic base in the United States. The patent specifically talks about using a centerfire Boxer primer but they also made a pinfire variation in 10g and 12g. Shells with different primers inside, different case lengths and varying brass base lengths are known to exist. Three 10g variations and a 12g example are shown above.
