410 overshot cards brands

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.

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 0.345″, the same internal diameter as a standard 410G 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.

I considering to punch my own overshot cards to accommodate a proper roll crimp on 410 shot-shells. But I"m having somewhat of a problem finding a good metal punch around .410 dia. with a pre-sharpened cutter. I"ve ordered a couple of punches from weapons/parts supplier catalogs in the recent past and have had to return them. (both were lacking pre-sharpened cutting edges) I"m not very gifted in sharping rounded edges. A flat blade I can sharpen up enough to shave with. But rounded cutter hardened punches are a whole different ball game for me. Does anyone have a supplier in mind I can mail-order a proper tool from? The punches intended purpose would be for> thin plastic disks .410 diameter.

As one who"s loaded 10,000s of .410-bore shot shells, I gotta ask, why a roll crimp? Stuffing 410s is a big enough bother, why complicate the process? Back in the day, my neighbor was moving and gave me a large carton of once fired paper .410 hulls and a supply of wads. I loaded the 5K hulls with the traditional card and fiber wads according the the recipe of the day. Compared to plastic hulls, with one piece plastic shot cup/wads, the papers performed dismally. Twenty flats of 410"s and there wasn"t a 25-straight in the bunch There"s a reason .410-bore competition scores soared with the introduction of the new ammo, it"s a quantum leap better. IMHO, as far as using a roll crimp on a .410, if you"re gonna re-invent the wheel, don"t start with a square one.

zippy 13: Why a roll crimp? >000 buck used in a tight fitting chambered shotgun is why. The recipe I have is a load not meant for your average weekend skeet shoot but it does call for (2) over shot cards .30 ths. each to be used on either the 2-1/2 or 3" hull loads involving 000 Buck usage. As you know any recipe that calls for a folded crimp can also with a little trimming of the hull in some cases accommodate a rolled crimp also. I have material here that is .60 thick. If cut right? would require only a single card inserted into the shot area which intern would offer a much better crimp support. The material I"ve intended on using is not paper as sold by B/P/I to their distributors.(midway) But plastic. I"ve found for my particular usage rolled crimps work much better in my weapon than any {reloaded folded crimp} does. I think it is due to the fact that most modern metal Crimp Rollers offer tighter tolerances and are less forgiving than those final stage crimpers found on most shot-shell presses these days. I guess I"m old school on some things zippy 13. I"ve found over the years progress and change is not always as good as some profess it to be. Again thanks, for your input zippy 13.

oneounceload. Thanks for the info. But 7/16-th. is to large in diameter and 3/8s is to small to use. The closes drill size I can measure to is >13/32th at .406-ths. In reality the actual measurement is no more than .410 ths. A 13/32 wad / leather cutter would be almost a perfect fit for my application. I"m wondering if there is a business that custom makes wad / leather cutters? I do thank you for your recent input though.

SSMcG, thanks for the heads-up on a different side of .410 reloading. I re-sized a cheapo Harbor Freight punch to cut over powder wads for my percussion revolvers. I have few metal working tools. I spun the thing in a drill press and used abrasives on the hardened steel. It took some while, but the results are satisfactory.

The BPCR folks use wad punches in reloading. Here"s a site with a selection of punches including .410" & a .403": http://www.buffaloarms.com/wad_punches_pr-3756.aspx

Hey there Don H: >Way to go!!!< Thank you Sir, for the site. They have just what I need in.410 dia. Not to bad a price either. I"ll check them out in the AM and place an order for one.-- 410 ga. 000 Buck load should preform flawlessly now, since I"ll have the correct tool to punch them over shot-cards with. Again "Thank you Donald." Sure Shot Mc Gee aka tom

These custom overshot cards come in a package 250 pieces. Three thicknesses allow loaders to achieve the perfect roll crimp regardless of shot size selected. They come in 8 different colors to visually identify your custom load quickly.

To be fair, I"m sure that loading .410 shells is more time consuming for the manufacturers. But, to me the shooter, it"s still hard to swallow 16 bucks for a box of shotgun shells.

So, the cheapskate in me decides to load one up; just to see how difficult it is. I have loaded 12 gauge shells off and on for years. I"ve always used a lee load all press and had good luck doing it. There is no load all for .410 and the mec loaders are pricey. Obviously that was not happening.

I have a bunch of spent shells. So, I decided to get into low cost reloading of the .410. I took out a punch and knocked the old primer out of one. Took a larger punch and pressed in the new one.

I"m far from the first person to do this. You can find a step by step tutorial at the end of this article. He"s using pyrodex, but the same process works for smokeless powder. Some folks load with the old fashioned fiber wads under the shot. You can certainly use either those or the plastic style. Over shot cards are cheap, but I prefer making them from cereal boxes. Compared to metallic reloading, shot shells are easy. If you have a drill press, it can be used as a press with bolts and such to punch primers out and press them back in. Some people roll a crimp onto the end of the shell. I think that is a neat idea, but in the case of the .410 I"d rather preserve the life of the shell and not work the plastic over too much.

UPDATE : I have found that using styrofoam cups to make over shot cards is by far superior to the cardboard. Much easier to punch out and it molds to fit the shell. So much easier to work with.
