[QUOTE="tbrice23, post: 1020297, member: 59502"] I make my own gauge from a case fired out of my chamber so it head spaces to my chamber. I drill and tap the flash hole with a 5/16×36 tap. I dont size the neck of the case so the bullet has no resistance when moving in and out of the case neck. That way i know that I am not pushing the bullet into the rifling. I place the bullet barely inside the case when i insert the gauge, when im sure the gauge is fully inserted i tighten the lock screw for the gauges sliding stem. Once it is locked i push the bullet and gauge out of the chamber with a wooden dowel of the appropriate diameter from the muzzel end. I then measure with a bullet comparitor and repeat until i have a truly repeatable measurement. If i have a large enough quantity of the same lot # of bullets for that rifle i can monitor and measure throat erosion and wear. If you're unclear about about anything let me know and I will elaborate further. ( i struggle with descriptives) [/QUOTE]
