"Not allowed FMJ here."
'Allowed' (legal) or not, FMJ should NEVER be used for hunting game animals.
The 'best' ( a relative term for certain) deer hunting ammo I've found for the 7.62x39 is Hornady steel case 123(?) grain SST. PPU round nose is OK but I've not found any rifle that feeds it well(not even a bolt action).
PPU Soft Points is very decent ammo. I have used it in multiple bolt guns and semi's without any problems of any kind. 2" groups are the norm at 100 yards.
I've also used Federal and Hornady hunting ammo in this chambering. The Federal gave me 1" groups, and Hornady by far the best groups at 5/8". These were shot from bolt guns. I've not found either available for quite some time.
If hunting hogs specifically, the common (and cheaper) European ammo loaded with bi-metal jacketed hollow points might be a good choice. In most paces, this is legal and from limited experience, it will expand (or tumble, hard to tell which) in critters. I/we shot a few deer with this bullet and all were full penetration with limited internal damage but the deer were recovered so they did work.
