Yes it is- 7.62mm is also called 30 calibre and is 3/5ths the diameter of the Browning 50 cal. 7.62 is the older NATO standard round diameter, from 30-40 Krag, 30 Springfield , 30:06, 30M1, 308, and now 300 WinMag. Also the commie blok SKS,AK47 and Dragonoff. Currently replaced in NATO close combat arms by the 223- 5.56mm.
Actually, the 12.7x99 cartridge (also known as .50 Browning Machine Gun) is a much older cartridge than the 7.62x51 NATO cartridge and the 7.62x39 M43 cartridge used by the Soviet Bloc and client states. The .50 BMG cartridge was introduced in the early 1930s, whereas the 7.62x51 NATO cartridge was introduced in the late 1950s. It is essentially a shortened .30-06 (7.62x63) cartridge. Not all 7.62 ammo has the same diameter - 7.62x63 and 7.62x51 has a projectile diameter of .308 inches (7.82mm); 7.62x39 ad 7.62x54R have a cartridge diameter of .312 inches (7.92mm), etc.
.17 HMR is a smaller calibre cartridge than the .22. There are several firearms which use the cartridge. The Henry Golden Boy is a lever action rifle available in this calibre, just to give an example.
Smaller than 20mm.
No, there is no ebook library application better than Calibre right now
Nominally, whatever size the bore of the musket is, although musket balls were usually considerably smaller than the bore in order to reduce powder fouling in the bore. The British Brown Bess was .75 calibre (but fired a .71 calibre musket ball), the French Charleville musket was .69 calibre (these were also commonly used by what would become the United States during the American Revolution), the smoothbore Springfield Muskets were .69 calibre, while the rifled muskets were .58 calibre... just to put a few out there.
Yes, a .357 firearm can shoot .38 ammunition because the .38 caliber is slightly smaller than the .357 caliber, allowing it to fit and be fired safely in a .357 firearm.
No. The .243 is a larger calibre, and the parent case is the .308 Winchester, necked down to accept the smaller projectile. It's considerably more powerful than the .223.
In general, a .38 Special +P+ load can be more powerful than a mild .380.
Yes, the calibre refers to the diameter of the bullet. Therefore, a 9mm would be smaller than a 10 mm.
A 22 cal is too small for good self defense.Added:Small calibre ammunition may not stop an attacker immediately. Ballistic science enforces small calibre, .22 or .32, ammunition may bounce around in a person if it penetrates them at all. I would suggest ammunition commonly used by law enforcement, 9mm, 40 cal, 45 cal, or 38 cal, of a hollow point variety. But since we are talking about firearms for defense there is nothing better than a shotgun. Just racking a round into the chamber could stop an aggressor.What ever you choose, choose wisely and consult an expert before you make any final purchases.
yes because you can custom your bullet depending what your shooting
You will have to have it checked out by a good gunsmith. There is more than one type of 7.65 ammunition.
I have a model 100 in 308 and have shot Winchester, Remington and Federal ammo all with good results. I have not heard anything regarding a smaller chamber.
