Overshot Cards (500/bag)
*SELECT your gauge from the pull-down menu.
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.
Specifications: .030-.040" (thickness can vary +/- .005" due to material variation and humidity) Industry tolerances apply.
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.

|28 Gauge OS Cards solved my crimp issues||7/2/2022|
|I?ve recently begun reloading 28 gauge and really struggled to get consistent, well formed crimps. The Over Shot cards completely solved this issue. I now get very well formed crimps with much less force. The OS cards also ensure that no shot pellets escape.|

|Work good in 410 hulls and I also use them in 28 ga under shot in the wad to take up space on Cheddite hulls for a less concaved crimp.|
