Was digging around in the attic today and discovered a 2 lb. coffee can almost plumb full of '06 brass, all headstamped WCC52, still with the crimped-in military primers in place. After digging out my Wilson decapping punch and decapping them, I noticed that some of the cases have noticeably off-center flash holes. My first reaction, of course, was to go through them and trash everything with a flash hole that was obviously not in the center of the primer pocket, but then I got to wondering:
With a reduced charge spread evenly in the bottom of the case (I roll every case on the follower before I run it into the chamber), does an off-center flash hole have any measurable effect on accuracy? I go through a lot of trimming and weighing excercises to acheive as much uniformity as I can, and obviously a couple of off-center flash holes in a string of ten rounds introduces some theoretical non-uniformity, but has anyone ever actually done some real honest-to-God testing to see if it Does make a difference?
