Got it.

The way the one reply was worded, I thought there was some breakthrough moment when the annealing process changed, with a definite step in case quality evident from that point forward.

"ammo made before they figured out how to anneal the cases"

Maybe I just misread, or misinterpreted, it.

Thanks for the clarifications.

"Ammo made before they figured out how to anneal the case." That statement could very well apply to the 17HMR, but by the time the mach2 was born they had it figured out! They don't always do a good job of it though.
