Help remembering/finding case length tool
My Savage F12 (.223) chamber dimensions are bigger than my Wilson case gauge. So when I neck size only my brass doesn't go all the way into the Wilson gauge but does chamber in my F12 with no problem.
Being unable to use the Wilson gauge to quickly take a peek at the case length (also) I need a quick look tool to do that when I'm neck sizing only. I seem to remember a gauge/tool the looked like a big/wide metal ruler that had cut outs along the edge for various case/calibers. You'd see if you case would fit in it's specific slot... If not, trim. But i forgot who makes this tool/gauge (if there was one to begin with). Would appreciate it if someone does remember what I'm talking about. |

I believe you're OK continuing to use the Wilson gauge, provided the neck-sized case is simply longer from the shoulder reference to the base.
The critical dimension is from the shoulder reference to the lands. If your case neck fits and the neck has grown so it sticks out of the Wilson gauge, it needs to be trimmed. On the other hand, if the neck just won't fit the Wilson "tight end", then that's another problem. One solution might be to drill out the tight end a few thousandths. (Make sure no burrs are created at the shoulder area...) Then it should work as a case length gauge. And, unless your rifle has excessive headspace, it should also continue to work as a cartridge headspace gauge, for cases you have full-length resized as well as neck sized. I don't think the diameter of the "tight end" of the gauge is critical. However, if you really want the tool you described, I think this might be it - Lyman case length gauge

Thanks!
Yes that is it. I tried using the search function on Midway but got 50 pages of what i wasn't looking for. |

Hello, deepcore. If your going to be handloading and working around firearms..why don't you do yourself a favor and buy a dial or dig. caliper?
A good quality 0-1" micrometer as well? |

deepcore, I don't know the source of your brass. But I find on the 223 Wilson gage, most of the hang up is burrs on the head of the case. So before I check one in the gage, I insert it head first into the gage. If it doesn't go that way, I know I am not going to get an accurate reading.
The Wilson gage (directions attached) is specifically cut to allow fired brass to be used in it for headspace measurement. Brass fired in my AR's fits just fine. So you might check the head of the brass that isn't going in just to check. Last edited by jepp2; October 9, 2011 at 08:43 AM. Reason: spelling correction |

Sounds like you may need one of these from Midway.
Forster Headspace No-Go Gage 223 Remington If you have excessive headspace, I think it best to take care of that first.

As far as case lenght the Lyman case lenght tool will do the job, but not check for headspace. Jim

I have three calipers one set up for use with a Hornady OAL gauge, a second set for with a Hornady Headspace gauge, and a third plain for general measurement use. And I have a micrometer. All off them digital. My original post was for help finding/remembering the Lyman EZ Case Length tool. I can use my calipers I know....the fact that last night I couldn't remember the Lyman EZ bugged me. |

This is what you need to measure exactly what is going on with YOUR rifle and YOUR chamber.

It isn't large in all dimensions, so a nick on the case head can make the head too large to drop in, giving the appearance of a case that is too long to datum when it may not be. While I haven't experienced it, I suppose the case neck could also bind, preventing the case from dropping in. Is the "cartridge headspace" too large in this problem? Or is it the neck that's too big? (Just curious...)

I recently bought one of those Lyman case length measuring 'thingies', though my calipers worked just fine for years. What I found, to my disappointment, was that neither the 260 Remington or the 220 Swift was listed on the Lyman device. Maybe I got crosseyed and missed seeing them, so I'll recheck (for the 3rd or 4th time). I can forgive them for leaving the 260 off, but to leave the 220 Swift off is just flat unforgivable. Geez.

I just use my calipers. I lock it to the max length. If case does not go through it goes to the I will trim it later can. (4 one gal freezer bags full)
I shoot .223 and have so much already prepped FL sized brass I just load those, tnen neck size till they need to be trimmed. If I feel that the bolt is giving resitance after firing I just put those cases in the scrap brass bucket. I have too much of it as it is.

"Setting up full length resizing based off fired cases LE Wilson Preferred Method:" so I'd say that they expect fired cases to fit. However, if you have a chamber with oversized diameter, either near the head or neck end of the case, it is possible that they won't fit until they are resized.

Mc Killen & Heyer Inc. Case Length Gauge
I knew I had got one those gauges in a box of stuff. Mine is not a lyman it is a McKillen & Heyer Inc. about half the size of the lyman, no 223 but it does have the 220 Swift on it, right between 32/40 Win. and 244 Rem- 257 Rob.

This isn't a headspace issue. The OP is neck-sizing only and the case walls are not being reduced
in diameter to SAAMI standards. That the neck-sized case won't fit the Wilson gauge is no surprise, nor does it need to. If the case fits back into the chamber and the 12F bolt closes, you are Good2Go headspace-wise. I would, however, get a decent digital caliper if you want to check overall case length. |
