While doing a little online research for reloading 300 BLK I stumbled across these. If you're a person who likes to use a case gauge, you might find this interesting.

We've been using these for a while. They work well.

About 20 years ago, I got a .308 WIN case gauge from Midway that had a large hole in the side that you could see the shoulder contact area. I went back to buy other calibers and they did not have them anymore. I think the slotted case gauge is a good, practical modification.
