Not just the US, but all military forces- for the first time, you could fire and reload quickly- while not standing up! Breech loading firearms meant a rifleman could fire from cover, and not while standing exposed to enemy fire.
If you mean the US Civil war, matchlock guns were NOT used. They had long been replaced by newer designs. The standard rifle at the start of the war was a caplock. By the end of the war, breech loading firearms using metallic cartridges were in use.
The standard US infantry weapon was the Springfield muzzle loading percussion cap rifle fitted with a ring socket bayonet. Most of the artillery was also of the rifled muzzle loading variety. Cavalry troops used the breech loading Sharps Carbine, plus a sabre, and a percussion cap revolver. Officers also carried a revolver and a sabre in lieu of a rifle.
What you are asking about is a Model 1885. Depending upon when exactly it was made (the serial number will tell us that), it should be marked either "30 U.S." or "30 ARMY".
Under US law and regulations, ANTIQUE firearms are defined as muzzle loading firearms ( no matter WHEN they were made) andfirearms that were made before 1 Jan, 1899. If your drilling was made in 1911, it is not an antique under US standards.
Depends on where you aer located- different laws in different places. In MOST of the US, muzzle loading black powder firearms are not considered firearms under law- they are antiques- no matter when made- and the only requirement is that you be an adult. However, you need to check the laws where YOU live- and you did not tell us that.
In the US, a background check is required to purchase any modern firearm from a dealer. Modern firearms cover all guns except those made in 1898 or earlier, and muzzle loading firearms. This is a federal law, and applies to all states.
The receiver is the frame of a firearm- in modern firearms, it is the part that the barrel connects to. Antique firearms, such as muzzle loading rifles, did not have a receiver- only the lock, stock, and barrel. (Yes, that is where the expression came from) On a modern firearm, if it has a serial number, it is stamped on the receiver. By US law, a receiver IS a firearm- everything else is parts.
It depends on what you mean. There is no requirement to register firearms in the U.S.
If you mean from the United States, both the US and peru have laws regulating export of firearms from the US, and import of firearms into Peru.
There is no nationwide registration of ordinary firearms in the US. A few states have laws requiring registration of firearms in that state.
No.
