So, people get confused about that. Do they make them in a three-piece set or a two piece set? Average rating 4. Vote count: No votes so far!

Started with some handloads at the minimum load spec, and noticed the primer was beyond flat flowing actually , the case head was showing imprint from the bolt face, and to boot, the case separated.
Re-visiting, making sure I did not make any errors with the charge weight or powder used, I shot again, and the case showed the same symptoms, with a crack where the case started to separate.

The GO gauge should be flush or just below flush with the rear face of the cylinder. It should be less than the feeler gauge thickness that you noted earlier. Next, place the NO-GO gauge in each chamber. It should protrude enough that the cylinder cannot be closed with very gentle pressure. With a non-rebated cylinder, start by cleaning the gun as detailed above.
The cylinder should close easily, with no drag on the gauge, with a GO gauge in the chambers. If the headspace is correct, the cylinder will not close with a NO-GO gauge in each chamber. Do Not force the cylinder closed with any gauge in a chamber. Single action, solid frame revolvers have their own peculiarities. The area surrounding the firing pin in the frame is usually raised above the surface at the rear of the frame window. With the cleaned revolver on half-cock or in the case of a current production Ruger, with the loading gate open slip the GO gauge in the chamber and slowly rotate the cylinder.
The gauge should rotate past the raised section with no drag. Next, place the NO-GO gauge in the chamber and repeat the test. Carefully back rotate the cylinder as far as possible, remove the cylinder pin from the frame, and remove the cylinder from the frame. Replace the cylinder in the frame and repeat the test on the other chambers.
Shotguns Bolt action, pump and autoloading shotguns can generally be checked and treated like their centerfire rifle equivalents. Break open guns, whether side by side, over and under, or single shot types, must be checked carefully to avoid damage to the gun.
Start by checking the headspace with the barrel off of the action. The back surface of the GO gauge should be level with or drop below the level of the rim recess in the barrel being checked, while the NO-GO gauge should protrude above the level of the recess. After checking with the barrel assembly off of the action, reinstall the barrel assembly. Place the NO-GO gauge in the chamber being checked.
Very carefully and slowly attempt to close the barrel. The barrel assembly on a break open type gun can exert tremendous leverage upon closing. Snapping the barrel closed with a hardened gauge in the chamber can cause damage to the gauge, barrel and action.
The headspace that the original manufacturers of the M1 considered correct can be determined by checking new or nearly new rifles that we have here at CMP. With that information we have determined that Springfield Armory and the other manufacturers of the M1 used gauges that were very close to the Clymer dimensions closer than the Forster and therefore we use, and recommend using only the Clymer gauges. I have fired less than rds in this carbine since I bought it from you.

What is headspace? Headspace Gauges: There are a number of companies that manufacture headspace gauges, the two that are most commonly encountered are Forster and Clymer. For you guys that are kind of new to this game, a gas gun with tight or insufficient head space is FAR more dangerous than a loose one.
A gun that will eat a field reject gauge will at least go bang and function. Accuracy and brass life will suck, but you are not in any real danger. Partial or out-of-battery fires tend to blow things apart, including you. I thought there was some part of the bolt carrier that prevents the gun from firing until the bolt was in battery??? Was that not functioning? You don't even need a gauge if it won't go into battery with a selection of ammo makes; NONE of them fit.
