Most is a combination of the two. Like Wolf, Uly, Barnual, Vympel, Klimovosk, Novisibersk, they (at least their lead cored USA intended export rounds) have the hollow cavity in the nose like the M67, but the longer (more stable) jacket profile and boat tail of the M43. The only real M43 style around that i have come across is some of the old East German, Czech, and the chinese mil-surp steel core. M67 has a copper jacket, and lead core, with a flat base and air cavity in the nose.
The closest thing to M67 that isnt Yugo is the Romanian made "Hot-Shot" that century is importing. it has the true M67 style jacket with flat base and air gap, just with a bimetal jacket.
None that you listed are M67 btw, like i said they are all simply M43's with a poured in lead core that just happens to not fully fill the nose due to the flow propertys of the lead they are filling the jacket with. If you want real M67 spec ammo, but dont like corrosive primers and better accuracy, buy the Hot-Shot. If you want it all, buy real M67, its not any more expensive.
