OMG! Nutn makes 1 mistake and all here hate him! I do agree u watch 45 min for 10 min of info, however the dude I have probs with is Mac/Tim from Military Arms Channel.
Last yr. he made some tests on Body Armor and he showed it to be 3A but he called it level 2 despite the fact it said 3A on it and never corrected it, then in another vid same mike called 3A level 2 again, made some more vids with Armor penetration and on 1 he tested Liberty 9mm ammo and it blew the 3A to hell but then he took 1 round Bulgarian 7.62X25 Tok ammo and he was shocked about its damage.
Few months later tested more Tok ammo and gave wrong info about bullet weight etc.. and how hard its find surplus ammo, in his latest Armor test he uses PPU 7.62X25 against level 2 and it did not penetrate but he never one time mentioned the penetration of level 3A in his previous tests!
He don't know SH-T about Toks or the X25 ammo since anybody knows or should PPU ammo is so underpowered u got at best 1380-1400 fps where any other type gets 1650 fps + and 99% of X25 will defeat level 3A even the modern stuff, I do wish someone would test the "Rare M-48 Czech Steel Core Ammo".
In all my tests my M-48 ammo will defeat 3A, however I have never been able to get the fabled 1800+ fps from this 1952 made ammo, but 1450 fps at best!
