I haven't used PPU for 10-11 years when I used to shoot it through my ArmaLite. Function was good, the red sealant made a bit of a mess but if I remember right it was pretty slow.
M80-types seem to have a very wide variation in muzzle velocity. Going all the way back to the cheap surplus days (when I had a FAL) I've used Portuguese, Spanish, Hirtenberger, Australian, etc. Looking at the available ammo now and who has done velocity tests it appears much the same. I've seen as low as 2650 to as much as 2800 fps from a 20".
I use Fiocchi 308A for my blasting ammo currently. It is consistently over 2800 fps from a 20" and 2700 from a 16" and is in the same 50-60 cent per rd price range as everything else. LC M80C or M80CL is about the same speed and a little cheaper but has a magnetic bullet which I avoid for barrel longevity reasons.
At one point I stupidly got out of 7.62 x 51. I have a bad habit of getting really into one thing and then offloading other shit currently not being used to support that thing. Then a year later my interests have changed again. Getting out of 7.62 was really dumb though because of the price increases that took place and I was also sitting on a few 1000rd crates of excellent GGG ammo, which was expensive even way back then. I still had a lot of leftover stuff that I paid 120/1000ish too.....we'll never see that again. The GGG stuff wasn't the fastest but man, was it quality. Near match grade accuracy and I swear the brass was made by Lapua.
Anyway, "M80 ball style" ammo IMO is a very, very broad term. I've seen bullet weights from 143 to 151 grains, velocities from mid 2600s to mid 2800s (20-21"), magnetic, non-magnetic, and even silver colored projectiles in some German ammo. Accuracy from match grade (Australian, GGG) to 4 MOA.
