350 LEGEND: Use to check headspace of 350 Legend..
RIMLESS CARTRIDGE HEADSPACE: The proper use of Headspace Gages is the most reliable way to test rifle chamber length. Headspace in a rimless cartridge is the distance between the bolt face and a datum line, determined by SAAMI, where the front of the cartridge rests on its shoulder when the bolt is closed..
GO: Corresponds to the minimum chamber dimensions. If a rifle closes on a GO gage, the chamber will accept ammunition that is made to SAAMI maximum specifications. The GO gage is essential for checking a newly-reamed chamber in order to ensure a tight, accurate, and safe chamber that will accept SAAMI maximum ammo..
PRECISION MACHINED: Manufactured from top-quality, hardened steel and precision ground to ANSI and SAAMI tolerances. Headspace tolerance ground to a very exacting ±.00015. Each Headspace Gage thoroughly inspected with NIST-certified measurement tools to ensure the highest quality product..
MEASURING MEANINGFUL HEADSPACE: Properly speaking, and for safety purposes, one measures “headspace” as the difference between the length of a standard cartridge, as represented by a gage, and the gun’s actual chamber length , when the head of the cartridge is flush against the bolt face..

NO-GO: Corresponds to the maximum headspace we recommend for gunsmiths’ chambering new bolt-action rifles. This is not a SAAMI-maximum measurement. If a rifle closes on a NO-GO gage, it may still be within SAAMI specifications, or it may have excessive headspace. To determine if there is excessive headspace, the chamber should then be checked with a FIELD gage. The NO-GO gage is a valuable tool for gunsmiths’ reaming new chambers, in order to ensure tight and accurate headspace..

Beveled Finish Vial : Reduced the amount of sealing surface between the crimp seal and the glass surface,Also A bevelled top Headspace Neck might be required for some special closure systems (PerkinElmer).
Flat Bottom Vial: when vials have to run within the instrument on a slightly downwards tendency and preferred for manual headspace autosamplers,Flat bottom maximizes heating efficiency..

Jar funnel: Fits both regular and wide mouth jars.
Jar lifter: safely lift jars out of hot water with the Green gripping end.
Bubble remover and headspace tool: slide into the side of filled jar to release air bubbles and measure headspace.

Packaged 5 piece set in .002" increments.
Each shellholder is clearly marked to indicate the amount it will decrease case to chamber headspace.
Adjust case to chamber headspace of your reloads with a simple shellholder change.

FIELD: Corresponds to the longest safe headspace. If a rifle closes on a FIELD gage, its chamber is dangerously close to, or longer than, SAAMI-specified maximum chamber size. If chamber headspace is excessive, the gun should be taken out of service until it has been inspected and repaired by a competent gunsmith. FIELD gages are slightly shorter than the SAAMI maximum in order to give a small safety margin..
