Converting 556 to Blackout? Buy this

By . on Mar 05, 2023
Trimming 556 brass down to 300 Blackout can save a lot of cost and frustration as long as you create cases to spec. This gauge is what I rely on to make sure all are spec before loading.
Go ahead and look around the internets- this is the standard, no one makes a better product.

This is a must have product if you handload bottle neck cases. Instantly reports length from shoulder to head and also trim length. Can help trouble shoot troublesome sizing problems. I have these gauges for every rifle caliber I load. I wouldn't be without them.
