  1. 9mm Case Gauge

    Posted by Kevin on Apr 20th 2022

    These things are great. I just found a 9mm Makarov round that made it all the way through a 500 round 9mm Luger loading session. Didn't catch it will I picked up the fully loaded block to see one round sitting a bit lower that everything else. Don't know what would have happened if it made it to the range... But these case gauges are the final part of every loading session for me.

  2. 100 hundred round case gage

    A must for the competitive shooter. A little pricey but worth it for the time you save checking your reloads.

    Great for case gauging a lot of rounds fast.

  7. shockbottle case gauge

    This is pricey but very convenient for rapid assessment of case size when reloading from range brass. The shockbottle gauge is slightly looser than the Hornady one in .45 ACB, but effectively identifies cases with defects or bulges. Some can be subsequently repaired with a push-through system, but if they cannot, the round is disassembled and the case discarded. Better to be safe than have an explosion!

  8. Nothing but the Best!

    I used to measure each and every 9mm round in a single slot gauge. Then I got lazy and measured one every 10 or 20 rounds..... I hated doing that because all it takes is one bad round to ruin your day. I can now check 100 rounds and put them in the box in the same time it took me to hand check 5 rounds with the single slot checker. It is worth every penny. A+ product. I will order one up for 45cal next.

  9. Great Time Saver

    Loading for 10+ years, using a single round case gauge. Just upgraded and wow, what a time saver! Should have got one years ago.
