K&M collet .391

By John S. on Jun 13, 2024

I really like this product, wish they would have made it sooner so I could have purchased it sooner to use. The. 391collect is used in the K&M case holder. It will hold 223/ 300blk cases by the head for doing work on the case mouth, like chamfering, deburring and brushing of the case necks. Great saver for your fingers with short cases.
