Yugo 7.62x39 "ППУ 1987" trainer

I am told that this is a short range trainer. If so, why an elaborate projectile shape? East German short range trainers have a regular shape.


as an engineer you are moving between - often enough contradicting! - requirements, imposed by the purchaser(s). Just to name the most general: manufacturing cost per unit, set-up cost, distinction from other products, and other technical and functional features.

The DDR engineer found the “solution”, usually a compromise, you mention, the Yugoslav found the one in the picture.


I agree with Hans, there are many ways to achieve a goal and that goes for ammunition too. Just remind all the various short range projectiles in any caliber you came across. There might be not less than 10 designs (or even many more) for the same purpose.

Yugoslavia also had two 7.9x57mm short range loadings with similar bullets; the M76 with an aluminum core and the M80 with a lead core.

The Privi Partisan English language website listed the designations as Practice, M76 (“This practice cartridge serves as training ammunition for accuracy shooting at distances up to 100m in areas where standard ball ammunition cannot be used due to space limitations. The cartridge is identified by aluminum bullet tip”) and Practice Indoor, M80 (“Cartridge is identified by lead bullet tip”) before the Military Small Arms Ammunition section was removed from the site a few years ago.

The M76 in 7.62 x 39, 7.62 x 54 R and 7.9 x 57 is meant to be used up to 100 m with a maximum range of 500, 530 and 720 m, respectively. The 7.62 x 39 M87 and 7.9 x 57 M80 were designed for distances up to 30 m.

7.62 x 39:

M76 = 2.35 g (36 gr) - V25 900 m/s (±30) - Single-base extruded powder
M87 = 8.0 g (123 gr) - V25 270 m/s (± 20) - Single-base flake powder

7.62 x 54 R:

M76 = 2.3 g (35 gr) - V25 770 m/s (±30) - Single-base extruded powder

7.9 x 57:

M76 = 1.90 g (29 gr) - V25 830 m/s (±30) - Single-base flake powder
M80 = 6.0 g (93 gr) - V25 250 m/s (±30) - Single-base flake powder
