All New Case and Cartridge Gauge with Tri Step Face Design - Patented!
Now with Patented Overall Length Indicator Cut !
With our brand new advanced Patented Tri-Step and Overall Length Indicator design you will get the best most advanced cartridge measuring gauge made today!
The new design incorporates a cut in the base of the gauge that measures the minimum and maximum overall acceptable length for your cartridge.
Until now there was no easy way to measure the minimum acceptable overall length of your loaded ammunition. Now with this revolutionary design it's so easy it takes less than a second! Simply drop a loaded cartridge into the gauge and make sure the bullet tip doesn't extend past the gauge base or be less than the bottom of the groove cut in the base of the gauge
(see pictures for diagram explanation).
No longer is it necessary to measure each cartridge with your calipers, taking time and aggravation. This gauge DOES IT ALL! These new patented gauges measure all important aspects of your ammunition.
No need for multiple gauges or to measure each cartridge with calipers, this is an all in one gauge!
The Shooters Box case and ammunition gauges are manufactured right here in Malden Massachusetts, by American workers on American machines!
The Shooters Box case and ammunition gauges are manufactured right here in Malden Massachusetts, by American workers on American machines! Made from Stainless Steel and built to last a lifetime. Each gauge is manufactured to S.A.A.M.I. (Sporting Arms and Ammunition Manufacturers Institute) chamber / headspace specifications. The gauge will measure the maximum cartridge length (full overall length), the minimum and maximum case length, the maximum case diameter, the minimum and maximum headspace. and now will measure the minimum overall cartridge length! A loaded cartridge should fit freely and easily into the gauge. A cartridge that does fit properly may not correspond to the proper chamber dimensions.
The difference between the top step (face) of the gauge and the middle step shows the maximum allowed chamber headspace.
The middle step shows the maximum allowed case length. A loaded cartridge that is inserted into the gauge should not be higher than the middle step.
The bottom step shows the minimum allowed case length. A loaded cartridge that is inserted into the gauge should not be lower than the bottom step.
The bottom of the gauge indicates the maximum overall acceptable overall cartridge length and the ‘groove’ in the bottom of the gauge shows the minimum acceptable overall cartridge length. See the picture for more information.
Our innovative patented 3 step face design will measure the minimum case length (lower step), maximum case length (middle step), and also show you the SAAMI specs for maximum allowed chamber headspace (difference between middle and upper step which is the face of the gauge). See pictures for more information.
Place
a clean cartridge into the gauge and make sure that it completely seats
by itself with no assistance to seat it. The head of the brass should
sit within the lower and middle step of the gauge. If the cartridge
sits higher than the middle step then your brass might be too long.
If the head of the brass sits below the lowest step then your brass may
be too
short or the bullet crimp is too much. It's easy to check by eye or
finger
tip feel or with the help of a straight edge or steel rule. With the
cartridge in the gauge, check the backside to make sure the tip (bullet
end) is not protruding outside the back face of the gauge. If the tip
of the bullet protrudes from the end of the gauge
the entire cartridge is longer than the maximum allowed cartridge
length. If the cartridge does not easily drop into the gauge without
assistance there is most likely something wrong with the dimensions of
your cartridge. Any ammunition shown in the pictures is for

WARNING!!!
NEVER ATTEMPT TO RESIZE LOADED CARTRIDGES. THIS IS EXTREMELY DANGEROUS
AND COULD LEAD TO AN ACCIDENTAL DISCHARGE CAUSING INJURY OR DEATH.
In
some instances your cartridge may sit flush with the lower step BUT the
brass may be shorter than the SAAMI minimum specifications. In this
instance your ammunition may still fire and function correctly but it is
up to you to confirm this will not cause an unsafe condition. It is
the reloaders responsibility to determine the cause of incorrectly sized
cartridges and to correct it. In some cases ammunition previously
fired with maximum powder loads or with abnormally large barrel chamber
diameters may not fit this gauge. This is due to some resizing dies not
being able to fully resize the brass cartridge all the way down to it's
head. Any ammunition shown in pictures is purely for representation
purposes and is not included with the purchase of this gauge.
