I ordered one and received it today, can't believe I waited this long to get one. I reload lots of 9mm for practice and matches. I use to spend time, a day or two before the match, punk testing ammo for the match. I can now just check all my loaded ammo and put the stuff the fails into the practice group.
 
How many cases are you guys having fail? Interested in a percentage.

I have contemplated getting one of these. But having a hard time, honestly I havent had any rounds fail plunk after running through a lee fcd.
 
I stopped gauging 9mm and 45, once I started filtering out bad brass and roll sizing I simply didn’t have a bad round in 1,000 so I stopped. Of course it probably takes me about as much time to roll size as it takes to gauge them in the hundo.
 
I dont sort my brass, so it is very important that I case guage.

If you sort your brass, discarding all CBC, ammoland etc... then you will have less rounds that fail.
 
It's a "must" have tool for me. I fail 13 per hundred usually. Depends on how ruthless I cull my brass prior to loading.

I'll get 2 to 3 a hundred that fail case gage. Only a few of the failed ones failed to chamber during a practice session. But if one does fail at a match, it hurts bad, very bad.

Depends on my bullet diameter and whether I sorted brass.

In 9mm at .356 with unsorted brass 10-15% with a majority being CBC or S&B headstamps. Most domestic brass that fails has obvious issues, mouth cracks, extractor nicks, rim damage. I jump to 30-40% at .358. Sorted less than 5% same for .355 bullets. An abnormal amount of failures is a sign something has moved on my press.

I do not demand perfect gauge results just close, I have learned what will for sure run. I could be less picky, what actually fails is less than 1% of my rejects. I don't have any tight 9mm chambers.

I'm guessing you are using heavy bullets? I have very few 9mm that fail the case gauge (maybe 1 out of 100) but I typically only load 115 or 124gn bullets, so the base of those bullets don't go as deep as 147s. The 147s that I have tried bulge the cases more. I did a check of different head stamps and found that many of them taper the case walls different amounts, which would cause more problems with 147 bullets especially if seated deeply.

@Toprudder cast 133 with a short round nose or 155. The 155s being a lubed bullet have the added perk of sizing to .358.

The case wall thickness is greater on most of the imports right from the mouth.

I just toss into the practice only bin these days rather than chasing down the cause until there's a clear pattern. I'm the first to admit lazy.
