Here is a less known target load of the 7,62x54R cartridges:
According to a Russian page, this cartridge was used for a short period for the “running deer” competitions. Later it was superseded by the 6,5x54R round.
The bullet weight is around 6 g. To produce a longer projectile with this light weight the bullet construction is similar to MKVII British ctgs: there is an aluminium filler in the nose. Also note the “dot” crimps around the neck. Hstp is 188 over 58.
As far as I remember the muzzle velocity is around 1000 m/s, but thanks to the very light bullet, the recoil is light.
