762×33mm

762×33mm is a cartridge designation that is not widely documented in standard reference catalogs. The name suggests a 7.62 mm bullet diameter with a case length of 33 mm, but there is little reliable, publicly verifiable information about this specific cartridge. Consequently, precise dimensions, case type (rimmed or rimless), powder charge, chambering, and ballistic performance are not established in authoritative sources.

Design and specifications for 762×33mm remain uncertain. Some mentions in obscure or non-peer-reviewed material imply a bottleneck or semi‑bottleneck case and compatibility with standard 7.62 mm projectiles, but there is no consensus or measured data to confirm these details. Without standardized measurements, there is no accepted loading data or service specification.

History and usage of 762×33mm are similarly unclear. There are no verified records of official adoption, commercial production, or military deployment. In many cases where the designation appears, it may reflect mislabeling, typographical error, or confusion with other, better documented cartridges such as 7.62×39 mm, 7.62×25 mm, or related wildcat developments.

See also references for related cartridges include 7.62×39 mm, 7.62×25 mm Tokarev, and 7.62×54R. Given the paucity of reliable data, 762×33mm is of limited practical relevance to current manufacturers or collectors, and any claims about its performance should be treated with caution unless supported by primary, verifiable sources.
