well it is worded pretty shitty. i checked the source and Bill’s random site has scanned pages from “The small arms review” march 1998 for wehrmacht ppsh41 and it shows that 9mm has 800rpm and idk where that 750rpm has popped out in wiki.
The difficulties which arose with the development of the pistol “TT”, were mirrored in the quantity of ammunition issued for it. Prior to the beginning of the Great Patriotic War, the production of cartridges for TT was limited to a rather small amount. On the cartridge cases made in this period, head stamps are absent. The cartridges were produced only with a regular lead core bullet. The bullet jacket was usually steel, a tombac plating (an alloy of copper and zinc). A powder charge weight was selected using a calculation for obtaining, at 10 meters, a muzzle velocity of 420-450 mps. It gave a bullet energy of 2070 kg/sm2, at the same distance, equal to 60 kg/m, at a mean maximum pressure, which was not superior. The mean charge weight of P-45/1 smokeless powder (porous) depending on a consignment laid within the limits 0,48 - 0,52 grams. This was applied to equipment and the “VP” powder (Viscose, for Pistols), whose weight oscillated from 0,48 up to 0,6 grams. The grain of the powder P-45/1, was a dark green color in the form of a short, rather thick cylinder, whereas the grain “VP” represents a thin long cylinder of greenish color. This powder was used in cartridges made until 1946. The production of this ammunition was sharply increased in the 40s with the beginning of the mass issuing of SMG’s.
In 1941, for SMG, the cartridge with the “P-41” bullet was introduced into the inventory. The cartridge with an armor-piercing + incendiary bullet and well-tried steel core - for defeating enemy personnel, for firing at petrol tanks, motorcycles, automobiles and airplanes.
The “P-41” bullet , with a weight 4,3 - 5,1 grams, had a black tip with a red band.
In 1943 a cartridge with tracer bullet “PT”, with a weight of 5,2 - 5,5 grams was also produced. It gave a bright red line at distances up to 400 meters and was used for indicating targets in combat. The cupola of a bullet was green in color. The new plants, in addition, were attracted to production of cartridges with a regular bullet, since 1942, placed a head stamp of the manufacturer and year of issue on the cartridge case. And, since 1944, when the productivity of plants reached maximum, large plants, in addition to steel, put the month of manufacturing on the cartridge. Smaller plants put the quarter date of manufacture on the cartridge case. The increase in the issue of ammunition demanded plenty of scarce materials: brass for cartridge case and bimetal for manufacturing of shell cases. On the other hand, observance of specifications was not required of rigid long-term ammunition storage - they immediately went to the regular army. Such a situation allowed materials to be partially substituted. Four plants out of eight, releasing this category of ammunition, had run in production, cartridges with cheaper bimetallic cartridge cases, occasionally also steel cartridge cases without a coating. There were bullets with a steel jacket without a coating or plated by brass instead of tombac. Engaging new plants in the manufacturing of cartridges, before not releasing ammunition and usage of simplified military technologies lowered quality of production. Later, once after termination of the Great Patriotic War, the remaining ammunition issued up to 1946, was practically completely given away to troops for practice firing or were destroyed. In the post-war time, the production quotas of ammunition were sharply reduced, many plants starting peace production. Because of reduction of deliveries of a bimetal until 1949, the cartridge was produced only with a brass cartridge case. As of 1949, there was steel brass…(?) (Word here is not clear. Derivative from brass. Probably means a jacket plated by a lamina of brass. That is Galvanotechnics?) cartridge cases, the production which was finished by 1952, with restoration of the issue bimetallic cartridge cases, soon completely superseded brass. At the same time, modifications were made in the design of a tracer bullet. On a carrying on part of a bullet there is a small bench, length is augmented by millimeter and a little weight increases.
The last modernization of the cartridge was in 1955, when instead of the old lead core bullet, a new one was adopted with the cheaper and solid steel core. For preservation of the former weight, the length of a bullet was increased up to 16,5 mm. Since 1951, the new bullet, step-by-step, replaced, at miscellaneous plants, production of the old bullet. Except for battle cartridges, cartridges of a secondary role were also produced. During the post-war years, blank cartridges appeared. Instead of a bullet, it had an elongated cartridge case, pressed into a “star”. Dummy cartridges made prior to the beginning of the 50s, differed from battle ammo by two or three cross-sectional flutes on the cartridge case. Later, cross-sectional flutes were changed to four longitudinal. The corporations - developer of rifle weapon for the needs produced mock-up cartridges. From battle cartridges , minus the powder, left with the subsequent coating of the cartridge with nickel or cadmium.
also it shows performance of tokarev to be anywhere from 420m/s (1378fps) to 450m/s(1477fps) for TT
