I say this after using many Wilson Case gauges for years and if money was no object I would think about Innovative Technologies Digital Headspace Gauge.

I’m surprised bozo699 didn’t mention this gauge also and put dancing Hula girls in his posting. :

The only thing I don't like about Larry's tool it the name,...it is not a headspace gauge, either is any of the tools mentioned on here, there for checking what is needed for shoulder bump and has absolutely NOTHING!! WHATSOEVER!!! with headspace, there are seperate tools and methods and tools for that.

DanConzo said:You can use the Wilson gauge on your granite block stand with dial indicator. You can always return to zero when changing from another cartridge by zeroing the top of the gauge and it will repeat the same readings It's foolproof and the Wilson gauge is still very well made. You disregard trying to sight or using a straight edge or calipers on the gauge and if the case is below or above the top of the gauge surface it don't make any difference with the dial indicator it still measures it.

Interesting - I stand corrected about precisely measuring shoulder set back with a Wilson Gage, I just never envisioned using a dial indicator in conjunction with the gage but it seems that could work quite nicely.
Us old farts can appreciate the Wilson gage which drew attention to properly full length resizing. I've use mine for more years than I'd like to admituntil I switched to the Hornady system.
Yes this is a headspace gauge, all the other tools mentioned are for measuring the case from base to datum line for the purpose to bump the shoulder back and nothing at all to do with setting the headspace on a rifle, I have also used a case to set the headspace on a rifle and it worked out fine for me, you can call it headspace if you want but it is terminology, my friend Boyd Allen once told me the difference between Jam and touching, and it again is all in terminology, when your trying to tell someone say about headspace and there thinking shoulder bump then your not on the same page with each other and it's all because one of the two learned the wrong terminology, Bumping the shoulder back to keep proper headspace between the case and chamber are related to one another of course but two different things,..peas and carrots may go together, they may both be a vegtable but there not both grown from the same plant!bigedp51 said:bozo699 said:Biged,

Ok I'm game, if you can measure chamber headspace which is the distance from the bolt face to the datum line in the chamber. WHY can't measuring from the base of the case to the shoulder of the case be called cartridge headspace and have something to do with headspace.
I don't know how well versed you are but at SavageShooters.com the brotherhood of the barrel nut uses cartridge cases and scotch tape to set their headspace. They also cry when they can't close their bolt on their full length resized cases. :'(
P.S. The headspace gauge in the photo below is a GO gauge and is used for a zero reference point for case headspace readings.

Also note that cases fired in gas operated rifles can end up longer than chamber headspace after they are ejected, and measuring shoulder bump gets tricky.![]()

I definitely agree with this statementDanConzo said:If the case is too long and bottoms out,you can use the Wilson or other make chamber type seating die base which is machined very well with a big hole on the bottom because it is made for the head of the case w/ a primer relief hole, just put it under the gauge (gauges are 1" dia and the bases hold them just like the 1" dia chamber seating dies) or if checking the case headspace after sizing you can trim the case first. These Wilson tools are very universal. There are many things you can do with the trimmer set-up too. One reason why is the quality built into them-their diameters and surfaces are held within .001". At least my Wilson stuff is.
Okay,DanConzo said:No use even discussing terminology here--most people know what we are talking about. I think most everyone knows what we are addressing here especially the OP.
Ed,bigedp51 said:Actually what we are doing is trying to keep the "air space" or "head clearance" between the bolt face and the rear of the case to a set minimum.

The red and yellow areas below represent the case stretching in the web area because we have too much "air space" or "head clearance" as the case stretches to meet the bolt face when fired.
(unless your name is bozo699 and you lube your cases and double your bolt thrust) :
And the area in between the quotation marks is called a "Bazinga". ;D

And excess headspace has many forms.......................................
and this is what happens when you let bozo699 pour your beer.
