shotshell overshot cards manufacturer

Place an overshot card on top of the shot charge just before crimping to improve overall crimp quality and seal in small shot and/or buffer. Excellent for use with BPI Roll Crimpers.

Our testing lab has proven that poor crimps can alter the performance of an otherwise good load. Overshot cards always produce better, more consistent crimps and this consistency is demonstrated in the standard deviation of loads in our lab. Our ballistic lab recommends overshot cards for better crimps in all loads.

Clear Overshot Disks(either plain or printed with shot size) are also offered for great roll crimping options. See pictures in Additional Images or click on this link.

Shotshell size selection: Use the same size gauge as your hull. Smaller diameter cards also work if your particular size is out of stock. For example, a 20ga overshot card works in a 16-gauge shotshell and so on.

Overshot cards are placed on top of the shot column, just before crimping. Overshot cards aid the load"s combustion process. This produces more consistent pressures and velocities. Also, overshot card wads help the crimp to contain the payload (buffer) and keep contaminants and moisture out.

Back in late 2017 I began work on a press-mounted tool for punching my own shotshell filler wads and overshot cards. After an initial prototype and two revisions, I’m happy to report it’s finally complete, and in production. I realize not everyone has seen my previous articles on it, so today I’m going to walk you through the final version, including the features and construction, as well as an explanation of how it works.

Finally we have plastic blister packaging. Although not biodegradable, I really like having a transparent option on hand when I need something as an overshot card. Once again it cuts smoothly, and easily. The material demonstrated above is actually plastic from grocery store salad containers if you can believe it, however thicker packaging not only punches well, it crimps even better.

The finished filler wads measure 0.650″, the same internal diameter as a standard 12G shot cup, and an equally excellent size for use as overshot cards. With a good supply of these on hand, it’s no trouble at all to customize my shot columns by placing them above or below my shot or slugs. Likewise, if I’ve got a difficult load to crimp like low-volume birdshot or roundball slugs, adding one to the top as an overshot card makes things a snap.
