Talk:13.2×92mmSR

Semi-rimmed in automatic weapons

The article states that the round was semi-rimmed, which "makes it sub-optimal for an automatic weapon". Several automatic pistol cartridges are semi-rimmed and some are also used in submachine guns like the Czech Skorpion (32 ACP). Both the British .303 and the Russian 7.62x54R military rifle rounds are rimmed and still in use in various machine guns, beginning with the venerable Maxim and currently continuing with various PK derivatives (PKM, PKP). The feed system for a rimmed or semi-rimmed cartridge is different from that of a rimless round: the cartridge is extracted backwards from the belt instead of being pushed through it, but this is not an insurmountable problem as proven, e.g., by the British water-cooled Vickers machine gun M1912 in .303, which could sustain an unbelievable amount of continuous firing without jamming or breaking down.--Death Bredon (talk) 21:00, 13 March 2020 (UTC)

Influence on .50 BMG

Who is it who's so blasted eager to get it into print here that this cartridge was some influence on the development of the .50 BMG no matter how tenuous the connection? John Browning was perfectly capable of having ideas. SlyGuyFox (talk) 00:04, 17 September 2021 (UTC)

According to this site the .50 BMG was inspired by the 13,2x99mm Hotchkiss, although actually created by FN Herstal initially for an anti-zeppelin browning machine gun. Since both the 13.2x92mm TuF and 13.2x99mm FN are in caliber 13.2mm, they have probably been mixed up historically at times for the origin of the .50 BMG. Although i cant confirm if the site above is accurate.--Blockhaj (talk) 10:50, 10 January 2022 (UTC)
