The AR-15 rifle has a fire rate of 800 rounds per minuteand a muzzle velocity of 3,200 feet per second.
A "Round" is usually how many shots are in the loading chamber. it can be one or many. A BB gun can carry 100 ROUNDS but only fires one ROUND at a time. A Machine gun fires many rounds in a "burst".
Some only carry 7 but mine hold 8. +1 if you keep one in the chamber.
If that is all you have on hand. It will likely burn off after several rounds. Synthetic motor oil is good to use on them. Buy one quart it will last you years.
