410 overshot cards free sample

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 use them to cut multiple layers of flannel to make cleaning patches in the diameters I need - they would work for making punches as well. I use a belt sander/disc sander to remove the hardened teeth from the hole saw and then sharpen the hole saw - i.e. bevel the "outside edge" of the bottom which will form a sharp edge and maintain the inside diameter. These mount on an arbor which usually has a center drill bit that is removable - remove the drill bit. Chuck the altered hole saw in your drill press and use a piece of wood on the table - lay your material down and drill through it with the hole saw. The hole saws usually have slots on the side and it makes it easy to stop the drill press, take something like a scratch awl and reach through the slot and push the patches/wad out - then cut another. If you are lucky enough to find a hole saw with the ID that fits you purposes - you could easily stack up three or so layers of thicker cardboard and cut cards or if cutting wads, cut up some 1/2" insulated sheathing or use a celotex type ceiling tile and get a lot of wads. Much easier than hand punching but just be careful to keep material flat on wood on the table so the hole saw has a backer when it breaks through the material you are using. If you leave the teeth on and try it, you"ll end up with ragged edges -- the teeth removed and the edge bevel sharpened on the outside will slice right through.If you know the O.D.of the wad you need for your bore/shell/use - take a set of dial calipers with you when you go looking for the hole saw so you can easily check the I.D. of the hole saw. As an example - remember that a 3/4" holes is designed to cut a hole that is 3/4" hole (.750). The thickness of the side of the material making the hole saw will have to be doubled and subtracted from the O.D. So as an example - a 3/4" hole saw that has sides that are say, 1/8" thick - the two sides would equal 1/4" that would have to be removed from the O.D. of the hole saw to give you the I.D. of the holes - in this example the I.D. would be 3/4" - 1/4" (1/8" of the thickness of the hole saw sides doubled) = and I.D. of 1/2" - which would be the O.D of the wads it would cut. Simplified but you get the idea.
