FMJ yaw and upset performance

[warped]

By the way - this is a bit off-topic but it might amuse you.

I was puzzled for a long time as to why the Italians necked-up their 6.5mm Mannlicher case to 7.35mm when they planned the switch to pointed bullets (which of course they had to step back from when WW2 started).

An Italian military historian told me the reason: they were desperately short of money, and had allowed their 6.5mm weapons to get into a bad shape with many having shot-out barrels. They could not afford to replace all those barrels, so they decided it would be cheaper to just ream out the whole lot to a larger calibre and cut new rifling grooves. So that explains the increase, and also the selection of the very odd calibre of 7.35mm...

Wow, what a monumental error, good thing for our guys though.
