PPS was a small company run by arron j lippman… who was busted by the batf for class 3 ,aow and other weapons violations and did federal time.
hi-vel made some all copper rounds for pps …called msc,map,mmc,…etc… they were in 25 acp up to 45acp. hi-vel is stll around and sells the 25acp & 32acp all copper rounds.
PPS made very few if any of the items they sold…re-packed bat bullets can be found for example.
The original 25acp msc used a brass bullet and was banned for sale by the ppa in 1986.
pps did goofy stuff like the 9mm map round had a .177 pellet stuffed under a plastic cap and sold as a exotic wonder bullet.
The hp .308 you have I have never seen…but pps did a lot of re-pack type things…and knowing a bit about pps they maybe just a standard .308 load.
The lower ap look to me like a pps re-pack of ABC AP rounds.They should have a grey teflon type coating on the bullet.
All ABC AP pistol rounds I have tested were VERY HOT like close to proof levels…very crazy some of it.The strory maybe the same with the .308 rounds
ABC was a off shoot of cobray and made a LOT of really odd rounds in the late 1970s and early 1980s…they went out of biz only a few years ago.
IMO…PPS service was a clown show but ABC was the real deal as far as exotic rounds made for goverment and other use. I know for a fact of 4 police depts that used ABC AP rounds in the 1980s…they worked.
Blast from the past…still in biz …the VERY last of the 1980s “exotic ammo” makers.
