Lyman 7832330 9mm Luger Pistol Max Cartridge Gauge

Works very well.

I am so glad I purchased this tool. I hand load a lot of 9mm and .223 primarily with once fired brass so every case has to be processed. In the past I measured each case with calipers, I found it relaxing at first but after a while it got to be more of a burden. Now I simply drop each case into the tool and it instantly tells me if the head space and diameter are correct, big time saver.It is also a safety issue. I buy bulk once fired cases and sometimes there are other cases in the bag. Just a couple of days ago I spotted a 9x18 makarov case in a batch. Probably would have missed it without this tool.Well made, aluminum billet cnc, accurate, very easy to use. Buy it.

This is a high quality gauge for use as a quick quality control check of your reloaded 9mm cartridges. Just insert the finished reload into the gauge; if it slides right with no resistance and it is seated within the milled slot (easily felt with finger tip), it is within SAMMI spec. It checks the maximum OAL and the case length in one simple step. Your desired OAL may be less than this maximum so it won't tell you if your getting exactly what you want but you will tell you haven't exceeded this maximum. I use this with every reload to insure I got it within spec. I also, periodically check with calipers for my desired OAL The cost of this gauge was lower than comparable brands. Thanks to Lyman for a quality product.

The the fit of this little case/cartridge checker is perfectly spot-on. It appears to be well machined from quality steel, which gives it nice weight in the hand, and the grip surface feels nice and positive.If you’re new to reloading, having one of these is a MUST, as it allows you to quickly and easily check several critical dementions of the case after resizing, as well as the overall completed round.I’ve compared this with other more expensive sizers from both Dillon and Wilson, each priced over $30, and honestly can’t see any real reason to pay twice as much.This gets the job done.

After multiple competitions where I had failures on my reloads I decided to stop being stubborn and ordered the 9mm checker. This now gives me a piece of mind that my rounds will chamber properly and won’t be losing seconds to clearing my weapon system due to a failure.It worked so well that I decided to also get a 100 round checker for my practice ammo.

This case gauge is excellent for determining if the overall cartridge case length is correct, which helps to avoid issues with excessive headspace. it is also good for eliminating cases that cannot be resized properly. (If you pick up range brass, some of it may have been used in firearms that don't completely support the cartridge and allow excessive expansion.) It allowed me to find three cases that could have created problems if I I had reloaded them.It may not be essential to have this, but the peace of mind it provides is well worth the cost.

Well made and accurate.

Great easy to use 9mm guage for competition rounds.
