Mule Deer, it's mostly your fault that I'm so hung up on straight ammo. I used to be happy when my ammo went bang when I pulled the trigger. Then you started writing about building straight ammo and how important it is ...
I agree....awhile back I had two 30/06's doing EXACTLY the same bad things,and began to suspect runnout per JB's articles.
Paying attention to runnout cured them both.This led to a rash of measuring everything,plus a pair of Redding Comp dies in 30/06 and 7 Rem Mag.
