Yes, 7.65 is the European designation for the .32 Automatic cartridge.
5.56 and 223 cal. are the same cartridge...........
40 cal ACP (not CAP) is the same as 40 cal. S&W. ACP refers to 'automatice cartridge pistol' wheras S&W refers to Smith and Wesson, who also make the 40 cal. cartridge....
the 30 cal luger cartridge has a bottle neck case. a mauser 32 cal cartridge has a straight case...........
The proper term is CARTRIDGE- bullet is the part of a cartridge that is fired from the barrel. There is no one answer to your question- it will depend of which .50 CAL cartridge- and then it depends on the loading of that particular cartridge (different bullet weights will have different powders/ amounts)
the 1917 colt revolver fired a rim 45 cal cartridge. however, half moon clips were used to insert 45 cal. auto shells and then place the inserts into the cylinder. In this manner both the 45 cal. rim cartridge and the 45 cal. semi-auto rimless cartridge can be fired from the 1917 revolver.
luger were made to fire a 9mm cartridge or the 30 luger cartridge. a 9mm cartridge will not chamber in a 30 cal luger pistol............
The outside of the cartridge case is .38. The .357 bullet fits inside the cartridge case.
NO,NO,NO,NO,NO.........you CANNOT shoot the 357 cartridge in a 38 special, but you can shoot a 38 special cartridge in a 357 pistol.................the 38 cal. cylinder was not made to house the 357 cartridge or take the pressure.............
A .70 calibre would be around 17.78mm. No such cartridge exists.
Yes. The .270 is simply a necked down .30-06 cartridge, and thus the action would be the same as the .30-06.
The smallest, best known centerfire handgun round is the .25 caliber (or 6.35mm). The practicality of the .25cal is questionable: you have all of the costs of a centerfire round, with not much more energy than a .22LR rimfire. In fact, nowadays, you are much more likely to find .22LR pistols than a .25cal. One step up from the .25cal is the .32 caliber. This is just about as out-dated as the .25cal, but there were some very popular weapons in .32 caliber, the Walther PPK (James Bond's weapon of choice) is said to be a .32cal (not a .380ACP). There are also pistols made to shoot rifle (long gun) rounds. These tend to be smaller caliber than a .25 cal, but are fairly modern (like a pistol designed to fire .17cal HMR).
