Quick question: I just got in a new 10mm Wilson Case Gage. I check the case prior to filling and the empty case slides right in (I'm using 1x fired)

I reload with a light crimp and note that my OAL is fine, but the filled case won't fit in the gage...it sticks up about 1/4". However, it drops in my Glock 20 barrel with no issue.

Are Wilson Case Gages very, very tight tolerances or is this something I should be concerned about? I check each round to ensure it drops in my barrel.

Thanks in advance, Fellas!

Your Wilson gage is ANSI/SAAMI spec. Glock chambers, on the other hand, aren't. They're sloppy by design. If your handloads chamber fine in all the necessary guns, use the tightest chamber to gage the cartridge, not the case gage. Forcing compliance will only increase work on the brass, reducing reload count.

Many modern crimp dies include a chamber sizing ring. If yours has one, the round will likely fit in all but the most restrictive chambers.

Thanks!

When I start with the empty case, I ensure they fit in the case gage before I start. For the few 1x fired that won't fit, I'll run those brass thru the Bulge Buster die (and the brass then fits.

As I run the brass thru the various dies, a few will not drop in to the case gage but, they'll fit in my Glock barrel with no problems. It seems the powder-thru expanding (flare) die puts a slight bulge near the head case - and that's what is causing the bottom part of the coke bottle appearance where it's not dropping into the Wilson case gage.

Thanks again for the help!

You may want to consider "Pass-Thru Sizing"...Why? Normal sizing dies are radiused at the mouth of the die and carbide dies also have a generous radiused opening, that and the shell holder take up some of the space that doesn't get sized.

Redding and LEE make Pass-Thru sizing type dies...LEE's FCD with it guts removed is used as a "Pass-Thru" and uses a push pinthat pushes the brass up and thru the inside rubbing the carbide ring to size the entire case stem to stern. This will remove the bulges that don't get removed during regular sizing. After "Pass-Thru" sizing the cases will fit the case gauge. However afterwards normal sizing is needed to tighten up the neck tension and deprime the cases.

I use a Pass-thru system for 10mm, 40S&W, 357Sig and 9x25Dillon, also 45ACP.

Why do I do this to have 100% reliable feeding everytime any gun or barrel chamber.

Word of CAUTION...DO NOT reuse a case that has a distinct line ("SMILE"), this is an area that has started to shear on the molecular level and it can not be ironed out or fixed.

Good luck and be safe!

Adding to Shadow's good advice, the problem isn't the 'powder through expander' die. It just can't "bulge" the case wall or web area. Something else is wrong, like the case mouth. Most chambers aren't absolutely cylinderical, including chamber gages. Perhaps you are expanding too much, or crimping too little. Also, the Lee FCD (Bulge-Buster) can be safely used on loaded cartridges, to "finish" a round for an improved chamber fit. I don't know about the other pass-through dies, as I've not looked into it.

With a Barsto barrell. No smileys, no bulges, no problems reloading. Reddding Dies

Mmmmmm, Bar-Sto..... Those and Jarvis are really nice. May need to use a Bar-Sto for my LS project.
