making overshot cards factory

That is a great use of boredom. I have made over shot cards from just about everything including milk cartons, frozen food containers, house siding (Tyvek), and various plastic food containers.

According to the guys over at Ballistic Products, the overshot cards are supposed to help patterns. Some believe the overshot cards blow patterns, but my own very non-scientific testing I did not see any difference in patterns.

The overshot cards are handy for adjusting crimp especially with cheap or over-used hulls. They are handy for keeping shot from escaping from a pourly crimped hull, and are damned expensive from the commerical guys.

Overshot cards are very handy when you roll crimp unless you are loading pumpkin balls. Some reason the shot just pours out of the hull when you forget the overshot card with a roll crimp. Damn nuisance to unroll the crimp and scoop all the shot up.

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.

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.

I must say this here, there seems a trend appeared recently to fiddling about with crimp closures after crimping running a RTO over a folded crimp cards under crimps etc, as i said earlier by its self its perhaps not a threat but if coupled to other factors could be a problem,, and i don’t feel its of any advantage or necessary.

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.

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.

Overshot water wheels In an overshot water wheel the mill race brings the water to the top of the wheel, where it strikes the paddles or buckets and turns the wheel. This is more efficient because as well as the force of the flowing water, the...

Friend wanted to know if I could make business cards for him. After some trial and error this what he got. ...Of corse scaled down to .3 so it will be about the size of your palm.

Wanted a case for business cards. ...Prints quickly on mk MK2s. Fusion 360. I suggest you slightly size the top up a hair so its a snugger fit. 85mmx55mm business card.

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.
