Guns > Airspace in 7.62x39mm Bullets

This High Road thread discusses 7.62x39 vs. 5.45x49mm Russian ammo, and it includes this standard bit of gun lore:

The standard load for the 5.45 has a hollow air space in the tip. This makes the bullet form a "banana" shape and quickly tumble, causing large wound channels while retaining weight. The afghans called the 5.45 "the poison bullet" for this reason. I'm not sure if the commercial Wolf stuff has the airspace, but the military stuff is apparently quite good at stopping attackers.

Which is fine, except that most 7.63x39mm includes the same air space:

from left to right, the current 7.62x39 rounds: Ulyanovsk EM1 match (my fav round, accurate and yaws quickly) Klimovsk FMJ, Klimovsk "Silver Bear" FMJ (Identical), WOLF FMJ (note gigantic air gap), Barnaul FMJ, Uly FMJ, Early Klimovsk FMJ, Rare early brass cased TCW fmj.

The Uly must suck. No powder.

Wow, that's a lot of air in the Wolf ammo. Instant flatpoint on contact.

Considering that 7.62x39 is a ballistic twin for the old 30:30, I wonder how that bullet would perform on deer? Externally, it looks like a pointed FMJ, exactly the round you *don't* want to use, but it would probably perform as well as any flat-pointed solid.

Peel off that jacket and the lead core looks just like an LBT (on left):

Uncle: The Uly is California-legal. Duh!

I shot a nice 8-point buck with some of the Romanian pointed soft point ammo, 1 shot into the rear of the ribcage through the body exiting just behind the left shoulder. appox live weight 150-160# (est) he was on the ground before the brass. (nice thing about eastern European weaponry, the brass forms a secondary projectile travelling nearly as far and fast as the bullet lol. As anticipated, damage internally was not nearly as OMG as with an 8x57 150 gr @ 2900 but was entirely adequate and much easier to clean. The 7.62X39 has become what I carry for deer now in NW Arkansas. Range at impact was appox 60 yds.
