Custom Case Length Gauge

Custom case length gauges can be made for cartridges that fit an existing shell holder. We will need to know the desired trim length, and either the bullet diameter or a couple sized sample cases. The cost for this service is $15.00 plus shipping.

Current lead time for Custom Case Length Gauges is approximately 6 weeks.

While there is really no maximum caliber, the smallest we can make is .22. We can not make anything in 17 cal or 20 cal because it is too small for our cutter to trim. Check out our Quick Trim Case Trimmer system for these smaller cartridges.
