12 ga 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.

The clear overshot card for roll crimps. You"ll know instantly what is inside every load. This is an excellent topcard for spreader wads. The material is frangible and breaks up immediately upon shot thrust. The stable platform offers a near-perfect surface for ideal roll crimps -- every time. Use in any overshot card application. Designed with a pressure-relief notch for high-speed loading.

Purely by accident I discovered what for me is the best backing for punching wads. We built our deck from Timber-Tek, (I think that"s the right name). Consequently we had left over ends and butts just as if it was built of wood. I couldn"t find my piece of industrial belting I had used for years and got to examining a piece of the deck material. Seemed little hard to me but figured I didn"t have anything to lose so I "gave it a whack" with my punch and a florist box. Doggone stuff works great and didn"t dull the punch at all, which I thought it would do. Been using it ever since and have yet to sharpen a punch. What we used has one side in wood grain and the back side is smooth.

While reloading shot shells and using roll crimps, overshot cards are placed on top of the shot/buffer media to keep everything in the shell. ...Why buy them when you can print them for about 2 cents each?

This is an overshot/wad card cutting die. Insert this die upside down inside your press using a L-N-L bushing adapter. I"ve made provisions for adding a metal washer or other insert to beef up the cutting area. Reem the metal insert to 18.67mm.

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 the material in place it’s a simple matter of operating the press handle, and punching filler wads. Each one comes out the exact internal diameter of a standard 12 gauge shotshell wad. If I need to produce a lot and don’t want to make a mess, I just place a margarine container with a hole in the bottom onto the nozzle at the top of the die, and punch as many as I need.

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.

I’m really happy with how my punch turned out, and already working on designs for a 20G model. If things go well I may try some others like a 410, 16 or 28 gauge.

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.

While I have been loading BP into plastic hulls for many years, I have never loaded brass.  Not much different than what I am already doing except for sealing the over shot card.  Everybody has their favorite sealing material: Duco Cement, Elmers glue, water glass, bubble yum bubble gum, spit from a horned toad, etc.  And all of those methods work just fine.  What I am after, being new to brass shells, is the one that is the easiest to get right.  These are not going to magnum loads!  This shotgun is about 125 years old.  As much as I love a big boom, this will be loaded on the lighter side.  No sense beating up on an antique.

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.
