Case Headspace Gagues

[SteveW]

Folks, who's case headspace gauges are you using ?

I was over on midwayUSA.com looking at the Wilson headspace gauges and a reviewer mentioned that the things are made of unfinished steel and rust like a cheap nail.

That rang a bell with me, as I have to keep most of my tooling in sealed containers with desiccant to stop rust in my humid environment.

Dillon make stainless ones, so I was going to head in that direction, but thought I would ask.. The only other vendor seems to be Lyman..

Mine are all Wilson. Yes, they will rust if not PROPERLY cared for. I keep mine oiled and in origional boxes and have little trouble with them.
Haven't seen Dillons, but sounds like a good bet depending on price.

Don't think you'll go wrong with either. Picked up most of mine at gun shows and Wilsons are most commonly available.

In case you haven't run into this yet, I have sized cases that will gage correctly but won't chamber, so be sure to try your resized case in the rifle before loading up a bunch.

:uhoh:

Huh ?

The whole point of buying the gauge is that I am going to be getting into progressive reloading of 223 soon and was going to use the gauge to set up the body sizing die. What was the root cause of your rounds not going into the chamber ? Bullet seating depth ?

Yeah...that is curious.

Apparently, my RCBS FL die did not set the sholder back quite far enough. Die was screwed down to touch the shell holder. Another 1/4 turn did the trick. Maybe just a combination of tolerances in my dies and shellholder. I've talked to other reloaders who have experienced same situation.

I had loaded 100 rds before running into the problem. I had only tried the cases in the case gage. they gaged fine then and still do. But won't chamber in the rifle, FAL. OK for a Bolt gun, you can mash almost anything into them. Case lenght is 2.010" and base of cartridge fits between the two steps of the Wilson gage. Correctly sized, the base of the case is level with the lower step.

Also, my FALs are set up on the tight side. I' sure that adds to the problem. Not a big deal, just something to be aware of and maybe save from having to pull down loads later on.

Thanks for the clarification.

If you reload, you really should get an RCBS Precision Mic.

Othewise you are just guessing at your specs on base-to-datum-line on the shoulder.

Different lots of brass have differing degrees of elasticity. So, even if you keep your sizing die permanently locked-down in the press, your base-to-datum-line specs can differ.

Throw away that steel bullet thing that comes with the tool. The steel bullet thing is worthless. The micrometer tool is the good part.

I like the Dillon's over the Wilson's. Stainless rocks.

Well, that statement right there kinda puts the kybosh on the whole plan !

I was planning on buying once fired (mixed headstamp) brass and setting up the sizing die (on a progressive loader) to put the brass back to the minimum spec, and using the headspace gauge to set that sizing die up.

Is there enough spring in the brass to put a case out of spec, once it's been sized down to minimum SAAMI spec ?

Reloading really isn't rocket science (or is it.....little lead rockets...hmmm). Don't let all this scare you off. Not sure you need the headspace gauge to set up your sizer. I've never used one for that. Usually just set the sizing die to just touch the shell holder and call it good. Some say not to resize the case any more than absolutely necessary because it will wear out the cases more rapidly. I'm not too concerned about that. More concerned with the loads chambering. If I get 3 or 4 reloads out of a case I'm happy.
