overshot cards factory

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.

Our overshot cards range in stock thickness from .030" to .040", depending upon the gauge you select. Overshot cards are essential for roll crimps and they add the finishing touch under fold crimps to improve crimp quality and seal in small pellets and/or buffering materials. Our ballistic lab recommends overshot cards in every load.

When using a buffered load, I don"t use an overshot card. I don"t want any cards over my shot. I add a small, round circle of toilet tissue just to keep the buffer in place until I seal the hull after crimping. Some hulls might have a little hole in the middle after crimping. It just keeps any buffer from trickling out if I drop a load, knock it over or whatever before getting it sealed. Some people use Tyvek over the shot.

If you’ve been reading my articles for any length of time, you probably know I load a lot of shotgun shells using Lyman and other published data. Over the years I’ve also developed a large number of custom loads, many of which require filler wads or overshot cards to get the correct shot column and a good crimp. Although these aren’t the most expensive components on the market, they still add up, particularly if you need several per shell. To make matters worse, they’re often difficult to find, particularly if your local gun store stops stocking the brands you’re accustomed to.

With this in mind I’ve designed and manufactured my own custom punch for producing 12 gauge filler wads and overshot cards. The model shown in the video above represents my prototype, which I’ve been using and testing for quite a while now.

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 well, like low-volume birdshot or roundball slugs, adding one to the top as an overshot card makes things a snap.

OK, so I recently acquired a Belgian Hammered Double in 16ga.  I also managed to get hold of some Brass Shells for it (Thank you!).  I also have the full set of correct sized over powder cards, cushion wads and over shot cards.

now that we have successfully stuck/glued/soldered an overshot card in place well enough to not fall out under normal bumps and bruises.  How much of that glue comes out when fired and for the remnants how do you get them back out of the shell for the next loading?  If I am over thinking this too much, I cant help it... I"m an engineer.

My cousin is using long beards and they started leaking buffer in his guns chamber, so yeah it"s probably a good idea to waterproof hand load overshot cards.

The NC720 is very dense, tight, and offers some back-pressure that seems to give the shot more power when compared to lighter materials. Now that cards are hard to find, I"m punching my own and am looking for something similar to the Nitro Card (NC20). The description just says it"s made from .125" "specialized industrial board materials." They look a bit like masonite without the textured backing.

Only the very thin and light overshot card wads have ever been traditionally used on top of the shot to close the shell mouth of a roll crimped shell. Roll crimped shells open differently than a folded crimp. The shot collapses the thin over shot wad outwards from the center and pushes it out of the way as everything exits the barrel.
