I'm looking at the 7 hole EGW checker for 9mm and 223. Before I order I wanted to see if you guys knew of anything better.

I'd hate to keep that thing clean.

My one hole gauges work well for me in 9MM and .223, but the multiple hole gauges are surely faster.
 
I couldn't agree more Walkalong. I do the same thing, I think it's wise especially with 223/5.56. I think the 7 hole would help speed the process along a bit.

The guns chamber is better. On Walkalongs 9mm . SAAMI loaded ammo maximum is .391" - .007" This would seem to point to a sizing die problem?? A Lee Undersized Carbide Sizing Die may be needed? No way , am i going to check every case. But thats just lazy me. :)

From the link in my other post:
My 3 digit serial number EMP has a very tight chamber. It was actually slightly below SAMMI minimum when new. I sent it to SA. They ran a reamer partway into the chamber and opened it up to SAMMI minimum, which is still tight. They also polished it. All on their dime. Any 9mm brass that will pass my Wilson case gauge, will fit the chamber, but if it fails the gauge in the least, it will not. I now gauge all my sized brass before loading it. Any that fails the gauge gets scrapped. 99% of that scrapped brass would fit in all my other 9MM chambers easily, but I can't be sure it won't get fired in the EMP, and this way I know it will work in any chamber that is properly sized. My EMP runs like a Swiss watch, as long as the brass is .391 or less. .3915 is borderline, and .392 will lock it up. Sweet shootin' gun.

Should have been SAMMI max. :)
 
Anyway, I have tried three different 9MM sizers, so I don't think it is a sizer problem. It's just some brass has been over stressed by hot loads or generous/not well supported chambers, and since the sizers can only go down so far, it can't be sized to fit. A roll sizer would do it. It's only about 10% of range brass, and far less of my fired brass.

+1 for Walkalong.

If I have two rounds in a row fail to drop out, a swipe through the gauge with a patch usually puts the suspect rounds back in spec.

My P88 has a very tight chamber as well.

I check every round through a gauge.
Mostly to ensure proper function, but also vanity.
I do pride myself on my guns not to have any ammo related problems.

I may shoot like squat that day, but the gun worked just fine!

You my want to use one of the Glock Buster push through dies. I think i've seen them for 9mm.

As for the guns chamber check I couldn't agree more. For my Glock the chamber is way more forgiving than than my Wilson chamber gauge so I'm good there. But for 223/5.56 the guns chamber check idea for me is impractical as I'm loading for my AR.
 
JUST A NOTE:

Everybody reloads different I guess. Over a period of time you develop your way of doing thing that you feel are right and that you are comfortable with. I'm sure we all feel like our way is the best way. My way is not the best way I'm sure but here is the way I do it.

Once my rounds are finished I tumble them for an hour or so. I then separate the rounds from the media and dump the rounds on a large towel and roll them around a bit to wipe off any residual dust (I usually don't see any dust but it's a psychological thing for me). Then I dump the rounds in a cool whip container. At some point when I have nothing else to do like when I'm relaxing in my lazy boy or watching TV I'll drop them in a single hole chamber gauge. If they pass they go into another container if not I site them aside to discover why later. I have only set 1 aside in many hundreds of rounds. I then place them in a bullet tray and examine all of the primers to make sure I have no high or upside down primer. Never had one, but I check anyway.

Now, I'm sure that most would say this is a waste of time. Especially since I have only had one no-go in hundreds, if not thousands of rounds. But, it a confidence and quality control thing for me. It also satisfies my perfectionist anal personality. ; )

The 7 hole gauge I mentioned in the OP would just allow me to check 7 at a time instead of 1 and because I tumble before gauging the gauge rarely gets dirty.

Right? Wrong? IDK. Just the way I do it........

For pistols I use the barrel. I have case gauges for all the rifle rounds I reload for. I use them for setting up dies and checking brass when case forming. After that I will spot check some. Everyone is different and there is no "best way".
 
Hi, my name is LeonCarr and I am a casegaugeoholic :).

Every single round I load, rifle or handgun, gets gauged between seating/crimping and the ammo box. One more thing to ensure reliability.

I use one hole gauges for everything, typically if one does not drop in it is due to a nick on the rim. 99% of the time one swipe with a file cures the ill.

Just my .02,

I used a gage after having a problem. Seems the shell plate can set the shoulder back different amounts at each station on a progressive press. A must have to set/adjust the FL die. Or a comparator is even better.

Mine are tumbled, sized, then tumbled again because I started lightly lubing 9MM a couple of years ago, but it doesn't take more than a tiny bit of corncob or grit to make it fail to fall out from its own weight. I have to run a cloth through it every once in a while.
 
Seriously you guys check ever round you load in a case gauge?

I set things up and check a few and then just load, been doing that for years with multiple calibers pistol, revolver and rifle. What is there to check or change if your dies are set??

I never say never but can not recall ever having an issue with a round that did not chamber/function??

Yup, I do. I've seen enough gun stoppages in competition to know it is time well spent

I just did 1400 rounds of 9mm a couple of weekends ago and it didn't take 20 mins...maybe half an hour...with the 100 round case gauge from Shockbottle

It allows me to do several things at the same time:
1. pick out improperly sized rounds...they stand proud when you lift the tray
2. spot reversed primers
3. detect high primer...either by running your fingernail across a row or just looking at a shallow angle
4. spot .380 cases that snuck in...they'll be lower
5. spot bullet tension issues...looking underneath for long or short seating
6. quickly transfer into a MTM box...put open box on top of rims and turn case gauge over

I do start each session by running an alcohol soaked patch through each hole in the gauge and allowing it to dry
