Please tell us what the model of gun is
Assuming you have a cartridge with PS 81 on the back- all I can say is that it is a military cartridge, made in 1981. The PS code was used by 4 different countries, so can't really tell what cartridge that is.
Center fire- the firing pin is placed to strike the center of the cartridge. Rim fire- as the name implies- firing pin strikes the very edge of the rear of the cartridge- the rim.
Well, we CAN tell you that it is Italian, and lkely a military rifle- since Terni was the national Armory for Italy. Beyond that, we need some description.
The 98 models (Gewehr 98 and Karabiner 98) were all manufactured in 7.92x57. Some K98 carbines were later rechambered for the 7.62x51 NATO cartridge, but these are visibly marked as such. Somewhere on the rifle (usually on the underside of the barrel), there will be an importer's mark, which will identify the importer, country of manufacture, and cartridge the rifle is chambered for.
We can't really guess- your pistol was made by Fabrique National in Herstal Belgium- but you did not tell us the model or caliber.
I own a .22 Brownings rifle . Made by Fabrique Nationale. I am attenpting to resore it. The tube that goes through the stock for feeding rounds into the chamber does not retain the ammo rounds. It is a tube with a spring inside. What prevents the rounds from shooting out before inserting the tube back into the rifle. Anny info will be much appreciated.online 1127169@
sorry- not a lot of information out there. ONE answer may be a cartridge from the 1930s, known as the 303/22 Falcon. Found in Australia and Canada, it was a cartridge created by necking the standard .303 Enfield cartridge down to a .224 bullet.
Terni was the national armory of Italy- you likely have an Italian Carcano military rifle- but we can't tell you more without more information. Sorry-
Properly called the 7.62x54R, it is a (as the name says) a 7.62mm bullet, in a cartridge case 54mm long, and has a rim (letter R). Created in Russia and placed in use in 1891, it is the oldest military cartridge still in use by the military. If you search for "7.62x54R wikipedia", there is a good article on the cartridge. Power range is similar to the American 30-06 cartridge, but does not interchange with it.
The 7mm is a smaller cartridge. If your rifle is not marked with the caliber, have it examined by a gunsmith. They may make a casting of the chamber using a material called Cerro-Safe. The casting is measured with a micrometer to determine exactly which cartridge it is chambered for.
yes it is a .25 auto, pocket pistol, does it have any markings on it?
