The case is rimless and bottlenecked, with a long neck crimped over the lower driving band of the projectile.

The projectile of the 23 × 205 mm round, having three driving bands, was originally used and may still be copied, while later projectiles have two driving bands. The cartridge case may be of brass or steel. The round appears to have been developed from the 25 × 205 mm round described previously. The case is simply lengthened and adopts a more conventional pattern of extraction groove and rim. There was no increase in ballistic performance, and the change was probably made to simplify ammunition production and gun design. It is used with a 25 mm naval air defence gun, widely employed in the Russian Federation and Associated States (CIS) fleet, usually in the form of twin mountings. It was then distributed to other countries receiving RFAS patrol boats and other vessels. In addition to Russian and Chinese production, described below, it is probably also manufactured in North Korea , though no information is available. As far as can be determined this ammunition is no longer produced within Russia itself. Applications include naval air defence guns, also Chinese Type 61 naval gun.
