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.

SAAMI loaded ammo maximum is .391" - .007
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.
Chamber would be (.3913" minimum) + .004" i think you were correct the first time.Should have been SAMMI max
*Sigh* Hopefully I got the point across anyway.Chamber would be (.3913" minimum) + .004" i think you were correct the first time.
I'd hate to keep that thing clean.
You my want to use one of the Glock Buster push through dies. I think i've seen them for 9mm.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.
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.
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.But for 223/5.56 the guns chamber check idea for me is impractical as I'm loading for my AR.
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.I tumble before gauging the gauge rarely gets dirty.
Yup, I do. I've seen enough gun stoppages in competition to know it is time well spentRule3 said:Seriously you guys check ever round you load in a case gauge?
