Go easy, I'm a rookie with this reloading, these are my first attempts.
I actually set the resizing die too deep on my set up or test piece. I had wrinkles in the shoulder area
So I spun the die up a bit and tried again.
I measured COAL for my rifle by partially sizing a neck so the bullet was just snug then carefully closing the bolt on the cartridge. I did it several times and repeated an overall length of 3.26"
