I ran across this:
“4.6x30mm H&K - H&K’s answer to the 5.7x28mm FN. Based on HK’s experimental 4.6x36mm cartridge for the HK36 ACR in the early '70s, even retaining its unique Löffelspitz (spoon-nose) projectile”
I assume the spoon-nose is something intended to de-stabilize the projectile upon impact with body tissue. Does anyone have a picture of what the spoon-nose projectile looks like? Is this concept still active?
