my holeyer than thou rifle maker has convinced me that a few thousands out of square makes no difference, at ignition the case neck expands and does not touch the bullet as it exits the case, ??? the dude shoots a piece of AR500 .5" x .5" 9" long at 300 yards to proof his work, if he misses it is not when anyone is watching
