You simply insert the tool into the neck of your sized case and slide it until one of the diameters fits snugly. If it stops at the first notch (from bottom), you have 0.001 neck tension, 2nd notch 0.002, and up to 0.005.

Burstfire Neck Tension Gauges is a 5 Step Gauge, in 0.001 increments starting at .001 below bullet dimension. Example: .224 starts at .223 at the bottom, and up to .219. For precision loading, you typically look for 0.001 neck tension. So your case should all stop on the first notch of the gauge (from bottom). If it bottoms out, you likely don’t have enough neck tension. If you can’t insert it on top one (0.219), it means you have more than 0.005 and likely too much neck tension.

Burstfire Neck Gages

All I can say is: OUTSTANDING!!! It sure makes determining neck tension a lot quicker. I measured each step on the gages and they were spot on. Thanks Burstfire!!

Great piece.

I bought it with the handle, works wonderful.

Can't manage what you can't measure

I'm shocked at the variation this tool reveals! Simple to use.

Best guage to buy!

Fine quality tools to make your shooting a hole in one. Built to exact measurements per my calipers. This should help ease people's mind on the amount of neck tension they are getting per the die cycle. Recommend very highly.........

It's a quick check to see if you are getting even neck tension from different brands of brass
