The 9×53mmR is a Soviet‑designed, rimmed, bottlenecked center‑fire rifle cartridge intended primarily for big‑game hunting. It was developed in the mid‑1950s by M. N. Blum and entered production in 1962. The cartridge is based on the 7.62×54mmR military case, which is necked up to accept a larger 9.22 mm (0.363 in) diameter bullet.

Design and development
The cartridge was created to provide a more powerful hunting round while using the well‑established 7.62×54mmR case as a foundation. Two standard projectile types have been offered:
- Type A – Soft‑point (SP), intended for hunting animals weighing 250–500 kg.
- Type B – Full‑metal jacket (FMJ), suitable for game in the 70–250 kg range.
Cartridges are loaded with the Soviet smokeless powder designated VT (винтовочный пироксилиновый порох ВТ).
Service history and production
- Designed: 1955
- Production periods: 1962–1992; resumed 1997–present (post‑Soviet era)
- Primary users: Soviet Union, later the Russian Federation
The 9×53mmR has been supplied for export to various countries.
Firearms chambered for 9×53mmR
A number of hunting rifles have been chambered for this cartridge, including:
- Los (Ижмаш “Los”) bolt‑action carbine
- Medved (СОК‑9) semi‑automatic rifle (fixed‑magazine and detachable‑magazine variants)
- TOZ‑55 “Zubr” combination gun (rifled barrel over a shotgun barrel)
- MTs‑7‑09, MTs‑30, MTs‑109‑09, MTs‑110‑09, MTs‑111‑09 – various double‑barrel and single‑barrel hunting rifles
- TOZ‑84‑12/9,27 – over/under combination gun with a 9×53mmR barrel over a 12 gauge barrel
- Saiga‑9, Berkut‑3, VPO‑103, and the IZh‑94 “Express” produced in the Russian Federation
Relation to other cartridges
The 9×53mmR should not be confused with the Finnish 9.3×53mmR hunting cartridge, which shares a similar case length but uses a larger 9.3 mm (.366 in) bullet and operates at higher pressures.
Current status
The cartridge remains in limited production and continues to be used by hunters in Russia and other regions where suitable firearms are available. Its design reflects the Soviet practice of adapting existing military ammunition for civilian hunting applications.
