What is Headspace in cartridges?
Used as a verb, headspace refers to the interference created between this part of the chamber and the feature of the cartridge that achieves the correct positioning. Different cartridges have their datum lines in different positions in relation to the cartridge.
How is headspace measured?
To measure headspace, there are three kinds of instruments. One is called a “Go/No-Go” gauge. Another is a set of precisely ground and measured gauges, each .001 inch difference in size. And finally, a micrometer that looks like a headspace gauge. Each works differently.
What is headspace and why is it important?
What Is Headspace (and Why Is It Important)? Headspace is the distance between the back of a cartridge and whichever part of it controls the position in the chamber. The concept of headspace came with the advent of fixed cartridges. At first, the concept was simple: cartridges were rimmed and headspaced on that rim.

What does excessive headspace mean in a gun?

Why is my gun chamber so tight?
Powder residue and dirt can cause the chamber to be too tight. With some guns, too tight of a headspace merely causes a failure to go into battery, with others it allows firing out of battery with catastrophic results for the shooter. Significantly loose headspace doesn’t just degrade accuracy, it promotes case ruptures and head separations.
Where is the headspace on a bottleneck case?
Straight walled or tapered cartridges usually headspace on the mouth of the case, while bottlenecked casings use the middle of the case shoulder as the reference surface. With belted cases, a projecting belt is added forward of the extraction groove specifically for headspacing.

What is headspace in rifle?
What is headspace? In simple terms, it is the amount of room in the chamber for the cartridge to rest before it is discharged. The measurement is defined as the distance from the face of the bolt to what is called the “datum line,” which is a particular location on the shoulder of the chamber of a given diameter, and a stated distance from the face of the bolt. The idea is to provide enough room for the loaded round to fit, even when the rifle is dirty, choked with carbon or just not squeaky clean.
How much headspace is allowed?

How does brass resize work?
Re-sizing brass pushes the shoulder back to minimum (this is called the “shoulder bump” and it ensures your loaded ammo will fit your rifles) and the next time you shoot, the brass will be stretched again. The effective service life of your brass depends on how much stretching, and how much bumping you subject it to. If your headspace headspace is within accepted limits, you can get 10 or more loadings out of your brass before you start seeing neck cracks from work-hardening. If the headspace is excessive, you may only get two or three.

Other dimensions like overall cartridge length and base diameter are also significant for proper fit of a cartridge into a firearm, and may be included as part of a headspace gauge. Cartridges very close to chamber dimensions generally offer superior accuracy, but slightly undersized cartridges load more smoothly and reliably under variable temperature conditions or when fouling accumulates in the chamber or cartridges become corroded.
