Very nice info on this round.

It still intrigues me, but I'll stick with bigger, slower, and heavier.

A bogus SD round! I am tempted to have you test a .22 Jet 1963 4"revolver against it for a reality check. Nobody but a loony ever suggested the .22 jet was a good antipersonel round, being the sane folk then knew they worked ok on pasture poodles ect. and strained on dogs!:p

Just a suggestion. You might check out EliteAmmunition.com and try out some of their 5.7x28 ammo, especially the S4 SuperRapTOR.
