12 gauge overshot card supplier

Our custom logo overshot cards are the favorites of our ballistic lab. We use a heavier stock material (.045") and apply a water-repellant coating to both sides. The result is an attractive and highly functional overshot card.

Use: Simply 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 BPIRoll Crimpers.

Excellent for roll crimpsOur 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.

Circle Fly wads have recently been improved. The 1/8” nitro card wad is now 100% waterproof, so it may be loaded in black powder shot shells using lubed cushion wads and the moisture will not soak through the nitro card and foul out the powder charge. The overshot card is now thinner and lighter, but stiffer; it is .025” thick instead of .030”, but is not made from a laminated stock like the old one was, so it is actually stiffer. Wad size .740.

The price to quantity is second to none! I have completely switched from BPI overshot cards to Dixie Gun Works! plus they are a true .025" thick card were BPI"s cards mic at .040" which makes a world of difference on some of my more particular buckshot loads crimps! Thanks to the team at Dixie Gun Works!

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.

Originally designed this unit to punch corrugated cardboard, so that seems like a good place to begin.  The punch works quite well with standard corrugated cardboard boxes I’ve cut into strips.  It’s a fast, simple process that yields nice, concentric disks.  Cardboard works great for buck and birdshot as it’s dense enough to take up slack, but flexible enough to compress during loading.  This is critical to obtaining a professional looking crimp with even the trickiest loads.

Next up is craft foam.  It’s not really my first choice due to it not being biodegradable, but I know some folks really like it, so I have confirmed the punch will work with it.  As with the cardboard and cork, it punches very easily, although the edges aren’t quite as smooth as the denser materials.

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.

The Gauge System in Shotguns: "Gauge" is a archaic English method of measurement of bore diameter based on the quantity of lead round balls of a certain size that would equal one pound in weight. For instance, a 12 gauge shotgun has a bore diameter of .729", and 12 lead round balls of this diameter will weigh one pound. Thus, the smaller the number, the larger the bore diameter. The one exception is the .410 shotgun, which is the true bore size in thousandths rather than a gauge measurement.

This may be used as a guideline for muzzle loading guns as well, although I recommend starting with a lighter load and working up. For instance, I use a 16 gauge load in a 12 gauge muzzle loader and find that it works very well, plus it is more pleasant to shoot. Outside of turkey or waterfowl hunting, it is not necessary to shoot full service charge. The standard British velocity with black powder was 1050 f.p.s. which was found to give the best patterns.

Loading through Choke Tubes: This is a problem that never existed in the muzzle loading era. Choke boring was not widely used until 1875, which was well into the breech loading era, where you did have to worry about getting down past the choke with the wads. After choke boring became available in breech-loaders, some live pigeon shooters who wanted to continue using their muzzle loaders had their guns jug (or recess) choked. This consisted of reaming a recess into the bore that was larger than the bore diameter, about 6" long, starting back about an inch from the muzzle. The shot hit this area, expanded, and then forced the shot back down to original bore size, creating the same choking effect as our modern constriction style chokes. Now, some new muzzle loading shotguns have screw in chokes. This provides the choking effect, but loading down through them becomes a problem. The difference is, that the wads used in the jug choke were matched for the bore size and going through the recess was no problem. A full choke 12 gauge gun has a constriction of .040", which makes the bore size at the muzzle a 14 gauge. Since the overpowder (nitro) card seals the powder gases, it has to be 12 gauge or the gas will blow by it and the load will not create sufficient pressure to shoot well. There are two possible solutions to this. First, load your gun before you screw in the choke tubes. This may work if you are hunting and don"t expect to fire too many rounds, or, second, place the nitro card on it"s edge and force it down through the choke tube with a ball starter, then tip it over flat once you have gotten past the choke and seat it on the powder. This does the least amount of damage to the wad, by only flattening it on 2 sides. The fiber wad can be undersized, for instance, using a 14 gauge fiber in a 12 gauge full choke gun, as the fiber would be destroyed ramming it through the choke. A 12ga. overshot card is thin and flexible enough to go through a choke tube without damage.
