I am in the process of working up a new minor load for an open Glock. I figured out how long I could go and still fit in the glock mags 1.155 now that I know it will fit in the mags I try the plunk test and works great. So after setting my crimp die I load a few with now powder or primer and try to case gauge them to find out they will not case gauge???
I am using an everglade 115gr jacketed hollow point bullet with similar profile of Montana gold bullet. I throw a few of my current minor load bayou 124gr round nose loaded out to 1.160 and the gauge great.
I am thinking that it is the profile of the bullet and am figuring that if it passes the plunk test I'm good to go??
I will post a couple pics
