Best Headspace Gage

Forster Products 30-06 Field Headspace Gage

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..

Size: 22.5*46mm, the vial mouth outer diameter is 20mm,20 mm crimp seal finish are designed to fit most headspace autosamplers.
Material: Manufactured from clear Type I borosilicate glass, of which can withstand high internal pressure, the vials have a wall thickness of 1.1mm.
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..
