I picked up some new Winchester 30-06 brass (qty 50) thinking that new brass properly prepped would eliminate the most variables for a ladder test. First of I noticed this guy:
I knocked the burr off and it is definitely scrap IMO.
Another piece was actually shorter than the trim-to-length. I trimmed it a thousandth less than the book value and still didn't have a new surface all the way around the case mouth.
And one piece has a small divot on the mouth much like the one pictured above even after trimming.
Then came the issue with the cartridge not being perpendicular to the surface of the head. I had cases that would walk all around the pilot if I rotated the case in my RCBS trimmer. Probably a quarter were off center by at least 1/32".
Is this normal? I know Winchester <> Lapua but this seems ridiculous.
