Real-World Testing: Putting Lyman Case Head Space Gauge .300 Winchester Short Magnum to the Test

First Use Experience

I first tested the Lyman Case Head Space Gauge .300 Winchester Short Magnum in my reloading room, immediately after resizing a batch of .300 WSM brass. I tested brass that had been previously fired in my rifle. The process was simple: insert the resized case into the gauge and check if it sits within the acceptable range marked on the gauge.

During testing, I did find that some cases were still slightly over the maximum allowable headspace even after resizing. This was eye-opening and confirmed my suspicions about my sizing process. With this information, I adjusted my sizing die and re-sized the cases, re-checking with the gauge until I achieved consistent results.

The gauge was very easy to use, and I didn’t need any specific instructions. I was somewhat surprised by the number of cases that initially failed the headspace check.

Extended Use & Reliability

After several months of reloading and using the Lyman Case Head Space Gauge .300 Winchester Short Magnum, it has become an indispensable part of my reloading process. The gauge continues to provide consistent and reliable results. I use it every time I reload .300 WSM brass.

There are no signs of wear and tear on the gauge, despite frequent use. Cleaning is minimal; I simply wipe it down with a dry cloth after each reloading session. Compared to my previous attempts at reloading .300 WSM without a headspace gauge, the Lyman Case Head Space Gauge .300 Winchester Short Magnum is a game-changer. My reloads are now much more consistent, and my rifle’s accuracy has improved significantly.
