410 overshot cards factory

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.

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.

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.

Since my 12G wad and filler wad punches went into production last year, I’ve received well over a hundred inquiries from folks interested in additional gauges. Without a doubt the two most often requested are 20G and .410 bore. With that in mind, I’ve been hard at work designing, prototyping, and testing four new punches to produce full-sized wads, as well as filler wads and overshot cards for both of these.

Beginning with the Filler Wad punches, these produce discs measuring 0.345″ and 0.530″, suitable for use in .410 and 20G shells respectively. These can be used either as filler wads to customize shot columns, or overshot cards for obtaining tight crimps.

Moving on to the wad punches; these will create full-sized .410 and 20G wads that can be used in place of a conventional plastic shotshell wads. These are ideal for anyone looking to load biodegradable, black powder, or brass hulls– or who just want to be able to produce their own components.

As of the publication date of this article, the 20G and .410 punches are $70USD each, plus $15USD for tracking shipping anywhere in North America. Alternatively, international shipping is also available upon request.

Not sure if anyone would be interested or not, but a while ago I got sick of being told my LGS was out of "specialty" shotgun components (non-resin wads, filler wads, cushion wads, overshot cards) so I decided to make a press-mounted tool to produce my own.

I"ve had a lot of inquiries about similar tools for 20G and .410; I doubt there"d be enough demand for me to make something in those, however if you know of anything similar please let me know so I can refer folks.
