I`m not quite sure what your asking?
Sorry, The 7.62x39 is pretty anemic when it come to velocity. A 150gr bullet will have a muzzle velocity of about 2150fps. When running at slow velocities such as this, bullet selection and terminal performance are key. There are very few bullets out there that will expand and penetrate at slower velocities.
Bullets like the Nosler Ballistic tip may work well, but they are very long and seating them deep enough to fit into the mag can be a problem. That puts my bullet choices in the 30-30 class. Nothing wrong with a 30-30 bullet like the 150gr Hornady RN, cept the low BC(.186) causes it to run out of steam and energy rather quickly. The 150 X .25RT Hawk bullet has a BC of .356.
Thanks
