Dimensions of russian 7.62x39 projectile

Sounds too technical for me and I don't know how much help this is but the 7.62 bullet is a .311 caliber (the 7.62x51 NATO is a .308) and I believe the usual bullet weight is around 123 grains with a muzzle velocity of appx. 2,300 FPS. This round is considered an intermediate caliber.

"Cartridges of the World" might be helpful as a printed resource but I don't know of any web sites with technical info. Maybe someone else can suggest something.

Projectile sizes and shapes vary. This is why they list BC for all bullets. For example, Uly match EM1 will have a different shape/weight than regular Uly FMJ, Wolf FMJ, Barnaul FMJ or Norinco FMJ. They all have different internal construction, different weight distribution, different deformation behaviors and different overall weights. When you increase the projectile selection to include SP, HP and that old cor-bon? (I think it was them) polymer tip ammo, 7.62x39 suddenly has dozens of possible projectile designs in the normal weight range. There are lighter and heavier variants as well.

There is a reason people use ballsitic gel isntead of computer simulation.

The Bullet is .311 diameter. You can load and shoot genuine .308's in it, but they'll not be teribly accurate.

Umm, that's not the projectile (bullet).

I managed to pull a bullet from a Wolf 7.62x39 cartridge. The inertial puller wouldn't touch it. With the collet puller, I had to tighten the collet down hard enough to slightly mangle it. The measurement of where the bearing surface ends and the nose begins is the one most likely to be in error from the damage caused by pulling the bullet.

And the bullet itself.

The squished-in part isn't a cannelure. It's the damage done by the collet puller.

I had it a while ago, there is a picture floating around of all the FMJ rounds sectioned. There is a huge difference between all the manufacturers. They all put the lead in different areas of the bullet. The jacket is mostly empty space BTW, especially in the Wolf FMJ which is basically just a shell in the front half.
