BPI OVERSHOT CARD 12ga .03"/.74"-Dia. 500/BAG

I use these for 12 gauge with a roll crimp, great product.

They do the job very well I will be buying more

These can turn an "okay" load into a great load--better crimps, no more escaped shot, and noticeably improved patterns and shot consistency. I prefer to use them with new, un-crimped hulls. They can be a bit difficult to get into the mouths of used hulls if there is too much memory in the hull material around the hull mouth. (But even so, they still work well, just harder to get in).

I don't necessarily use these to adjust load height. I load a lot of old 2 1/2" shells for my old Damascus guns and roll crimp them all. Of course you have to have some kind of overshot card to do that. These are great, as you can take a sharpie and do lettering on them. Much nicer than the ones I cut myself.

These are sturdy little cards that have come in handy when the wad is slightly too tall or the charge shot weight is a little aggressive. Also some plastic hulls leave a small gap in the center large enough for small shot to escape. I always keep them around.
