12 ga overshot cards pricelist

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.

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.

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!

Perfect for application and 28ga; I need a .55-.59 (14 or 15mm) cutter for 20ga though. The 20ga shell I did up above was “firm”, but it’s juuuust in there–I could move it with a screw driver to the side and pop it out. It really needs to be .57-.59″ to sit snugly underneath the roll crimp for 20ga. Here’s a plug cutter that is 5/8″, or .625, that’s just a bit too big but would cut plastic too. You want 9/16 punch or 14 or 15 mm.

Anyways, with a fat 20ga roll crimp (this was my first ever, on Win universal which is thin walled), this would work for 20ga; and certainly works good for 28ga. I’m tired of tool searching so I’ll leave someone else to find a 14 or 15mm hollow punch you can chuck in a drill for the “perfect” 20 OS.

I thought this could be a good thread to list the other parts/tools for making homemade fillers like OS cards, wad inserts of felt and thick cardboard. Here’s the ideas I’ve read or come up with:

Here’s a link to larger hollow punch, it has 9/16 (.56″) and 5/8 (.625). The 9/16 should work for 20ga OS while the 5/8 for 20ga nitrocards (used for 12ga load spacers).

Ok, bought the “plug cutter” 4 pack from Harbor Freight for $3.99, it works fine also, and the largest size is 5/8, which turns out to work fine for the 20ga. Again, please forgive the poor roll crimp, 2nd attempt ever, just wanted to show plastic disk in 20.

Having done the 1/2″ and the 5/8″ in 20ga, (8/16 and 10/16), the intermediate 9/16 would fit better than either. 5/8 is a tight fit at 0.625″. Round chambered fine in my semi auto and Citori though.

The importance of loudly declaring the OS plastic disc is “frangible”, is mostly to keep people from posting that it will increase pressures
