Found my notes on this subject from my customers rifle few years back what I came up with it was a lot shorter than I expected, he sent the box of ammo back to Nosler asking for an explanation all he got in return was a free box of shells, the shoulders on his box and the shoulders were really pushed back he had 11 out of 20 shells that way.
I didn't do any measuring, just eyeballed the rounds, but that's pretty consistent with my percent not firing. I would think Nosler would be concerned for customer relations and adjust their shoulders. Bad publicity can go a long way.
