Question on 7.62x39 steel case commercial ammo

[4306]

Obtained 1000 rounds of Wolf Polyformance 123 grain FMJ and after pulling a bullet and sectioning it noticed two things:

The bullet is FLATBASED not boattailed like Soviet M43.

Does this mean that the ammo has enhanced terminal ballistics (yaw) like the Yugoslavian M67?

The bullet has an airspace in the forward tip like the Soviet 7N6, which according to Dr Fackler, enhances terminal ballisics.

Does this feature increase yaw in this projectile? Thanks!

From my understanding, yes, the space up front will create quicker yaw in tissue. The flat base, I doubt but don't know for sure.

1000k rounds of WPA....mmmmmmmmmmmmmmmmmmmmmmmmmmmm...my Hellpup SBR is hungry all of a sudden. LOL!!!

The airspace up front shifts the center of gravity/balance point of the bullet aft, so once it impacts a target it's more likely to tumble through the target since the CG is aft of the center of the bullet itself.
