Detailed Description

BP Logo Red Overshot Cards 12ga (500/bag)

Our custom logo overshot cards are the favorites of our ballistic lab. We use a heavier stock material (.045") and apply a water-repellant coating to both sides. The result is an attractive and highly functional overshot card.

Use: Simply 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.

  • Overshot cards produce flatter, tighter crimps
  • More consistent load combustion and pellet containment
  • Effectively contains pellets within the shotcup during the firing cycle
  • Water-repellant
  • Seals buffer within the shell
  • Excellent for roll crimps
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 selection: Use the same size gauge as your hull. Smaller diameter cards also work if your particular size is out of stock.  Other uses see "Notes" section below.

Excellent Crimp Results 7/2/2022
So glad I found these and that BP provides them. They have solved all the crimp issues that I?ve had for years. Now, I have very consistent crimps and no escaped shot.

Ballistic products overshot disk 12/23/2017
I usually punch my own nitro cards and overshot! But Honestly these are a far superior fit! Makes roll crimping anything you want quick and easy! Also these disks Having ballistic products on them makes them just that much cooler! absolutely beautiful! Just loaded a bunch of t buck in a clbc wad and topped them off with this beauty! Roll crimped with your original roll crimper! Will buy more
