Fantastic info here on all sorts of Mak ammo.
FMJ is usually the better penetrator and my favorite was PS Grand (and one of the best, which is very hard to find)
The older corbon HP's were also excellent but are no longer made.
Corbon Powerball is promising. The Hornady is a HP with an under 1000 FPS velocity.
Unfortunately much of the Mak ammo is somewhat anemic, less than 1000 FPS velocity, on the good side the Mak is the AK of pistols, steel, brass, copper, stone or rubber cased ammo these things will usually eat them up and never miss a beat.
Some had problems with the 120 grain Silver Bear choking their guns.
