FMJ yaw and upset performance

[stanc]

It's true that the Norma 120gr FMJ load tested by AA did not begin to yaw until about 7 inches into the gel block.

As for your questions, I'd say:

1. Yes. By using either a two-piece core with lightweight (aluminum?) front and lead rear, or perhaps a design similar to that of the WWII 6.5mm Jap bullet.

2. Maybe. Although substituting copper or other non-lead material may not produce as rapid onset of yaw.
