Cop told me that the Hornady Zombie Max .223/5.56 was very good stuff, essentially the same as what they use. I understand that collateral damage figures into the equation. Also he said the DRT frangible was pretty lethal stuff.
I didn’t see any of the Herter’s 154 grain SP 7.62x39 in the quick skim of the link. Not seen any tests on it but looks like a fairly effective round. And it’s very reasonably priced, i.e. cheap & Cabelas usually has plenty. I can’t tell a bit of difference in recoil compared to 124 grain FMJ.
I will have to check those out. I’ve been searching for the best 5.56 mm projectile available from a self defense perspective for several days now. Lots of options. lots of opinions. lots of barrel twist rates. etc. One person will swear by a projectile and the next person will curse it. I’m liking varmint grenades too but, like everything else, opinions vary. I have personally seen them shoot what was basically hole for hole at 100 yards however.
