The Ballistic Tools case mouth and neck tension gage tells you exactly how much neck tension you will have with your reloads.

Stop guessing about your primer pockets. Know for sure with the Swage Gage ® primer pocket gage.

Gunsmiths use "go" and "no-go" gages to measure chamber tolerances, and now you can bring this level of precision to your reloads with the Swage Gage primer pocket gage.

Have you ever wondered if you are swaging or chamfering enough to fully remove a military primer crimp? Wondered if a primer pocket was too loose to hold a primer properly? Wonder no more.

I created the prototype of this tool for my own use in brass processing. I needed a way to quickly and easily measure primer pockets that was reliable and did not require wasting a primer. This tool has been indispensable for me and I would never go back to the old method of uncertainty and guessing.

One side of this gage is the "go" side which quickly tells you the depth of a primer pocket, whether any crimp is properly removed, and whether the primer pocket is loose. If it feels loose on the "go" side, use the other end of the tool, the "no go" side, to test to see if the primer pocket is too loose to hold a primer. If the no-go slides into the pocket, then you know to junk that brass before it creates the mess that a missing primer can cause.

Simply seating a primer in a piece of brass doesn't always tell you the whole story, since primers are subject to variations in size, they aren't a precision instrument. This gage is for .50 BMG primer pockets.

Ten Commandments

Set up your reloading bench where it (and stored components) will not be exposed to heat, sparks or flame.
Establish a comfortable loading procedure and don't vary it.
Keep your reloading bench, equipment and area clean and uncluttered. Label components and reloads for safe, easy identification. Never use powder from an unlabelled tin.
Understand what you are doing and why it must be done in a specific way.
Follow loading recommendations exactly. Don't substitute components for those listed in metallic data without reducing the load and working back up.
Never substitute smokeless powder for black powder or Pyrodex because smokeless powder is much more powerful than black powder. Never mix two powders together.
Wear safety glasses.
Stay alert when reloading. Don't reload when distracted, disoriented or tired.
Don't smoke, drink alcohol or take drugs while reloading or while in your reloading area.
Keep everything out of reach of small children.
