Case Length Headspace Gauge
For: 6.5 Grendel
CG-65GRN
NEW!!!

"The gauge allows you to see just how much you are sizing back."

One piece gauge that will check overall length to indicate the need for trimming,
datum to head length to assure correct headspace and to prevent oversizing.

Available for most popular rimless cases.

Note: 
Does not measure body diameters.

This gauge is intended to be used with fired cases
to determine a basis for full length sizing and trimming.

L.E. Wilson has been making precision reloading tools for 
over 80 years. 

The Case Length Headspace Gauge allows reloaders to 
measure case length from the base of the cartridge to the shoulder,
 as well as the maximum case length. 

This process shows the reloader if ammunition is being produced 
within  specifications.

Technical Information
Material: Steel
Features: Precision Machining

Notes:

This is a one-piece, non-adjustable cylinder-type gauge for checking
 fired and resized cartridge cases for cone-to-head and overall length

Used to compare cartridges against the minimum SAAMI 
chamber dimensions

The item description will indicate if the headspace gauge is Adjustable

Instructions:

Drop a fired case into the gauge. 

Take a measurement on headspace. 

This can be done with either a depth micrometer or caliper
 (Depending on if the case is sitting high or low in the gauge). 

If the case sticks out past maximum headspace the firearm probably
 has a larger than average chamber. 

The gauge can still be used because it is being used to determine
 how much resizing is required.

Now once the initial measurement is taken, slowly dial in the 
full length sizer until there is a 0.001 to 0.002 drop in headspace. 

This will give the measurement to resize the case just below the chambers headspace in the firearm being reloaded for, giving a more accurate shot and saving brass by not causing it to be overworked.

Once the brass has been sized, set the brass in the gauge and set 
the gauge on a flat surface with the head side facing down.

Now look across the top of the gauge, this give the maximum and 
minimum for trim length.
