Just to name one - JHP that really work, propelled at real speeds! OK, that was two!
And, to use two of your own examples, I can give you two more. Black Talons were first introduced in the 90s, just before my retirement. And Speer claims to continuous improvement of it's entire line. To me, both of these are new technology, neither of which were available to me in the Military.
A guy with your background should know that.
The flying ashtrays I remember were the 45 ACP loads with a hollow point so large that ability to feed them reliably was uncommon. So uncommon that being able to feed them was considered proof you had an exceptionally reliable 1911.New technology...
We had the flying ashtrays...we had fast lighter bullets ie: 125 grn 357 mags
Point of fact there is very very little that can be done...
Bigger cavity hollow points ...
Softer lead ...
Better jacket retention ...
