Very useful tool for the advanced reloader, or for a competition shooter who needs to know or be able to seperate rounds based on headspace length and or projectile ogive length.

headspace check is particulary useful for rifles with limited primary closing power like Ar15 AR10 and other semis, but not including SIG and H&K which have excessive closing force.

Experienced reloaders will know that even with a Full length die set at a particular height, when sizing mixed age and headstamped brass, that the effective headspace measurement can be different from case to case, case hardness can cause this, and short of annealing everything, this allows you to catch rounds that may not have had their shoulder pushed back fully, which will cause a stoppage, or a totally jammed round in the chamber.

This is not a tool for thickies, you have to understand what you are doing, and fully read the instructions for best effect, in some cases you are looking at a comparison, rather than an absolute number.

With the lead tool for example the tool provides its own ogive to measure the camber, your loaded round is measured against that ogive, which is a bit different to the stoney point system
