Case Neck Gauge # 26400

Possibly one of the most important tools you will ever use!

A quick and easy way to sort cases by neck wall thickness and uniformity. This tool allows you to accurately measure the neck wall thickness of the cartridge case and determine its uniformity,

(TECH TALK- CASE NECK UNIFORMITY)
UNIFORMITY OF CASE NECK WALL THICKNESS IS AN INDICATION OF THE QUALITY OF THE CASE ITSELF. ANY LARGE VARIATION(over .0015") IN NECK WALL THICKNESS WILL GENERALLY INDICATE A SIMILAR OR GREATER VARIATION IN THE BODY AND SHOULDER OF THE CASE.THIS VARIATION CAN NOT BE CORRECTED AND MAY LEAD TO CONCETRICITY AND BULLET RUNOUT PROBLEMS.
MOST COMPETITION SHOOTERS THAT HAVE BEEN FORCED TO TURN NECKS TO PROPERLY FIT "TIGHT NECK"CHAMBERS WILL CONFIRM THE FOLLOWING: "TURNING THE NECKS OF POOR QUALITY CASES WILL NOT SOLVE THE PROBLEMS ASSOCIATED WITH THE POOR UNIFORMITY THAT REMAINS WITHIN THE SHOULDER AND BODY OF THE CASE."
AS IN ALL HAND LOADING PRACTICES-UNIFORMITY IS THE KEY TO ACCURACY.

Two mandrel sizes are supplied to allow measurement of all cases from .17 cal. to .338 cal. including cases with small (.060) flash holes. For your convenience the mounting base allows direct attachment to your reloading bench,

Pilot stops are required for each caliber . Two pilot stops are supplied with the tool, #06121,.22 cal. and #06130, .30 cal. More Pilot Stops Sold Below.
