Ok all you experts out there, I have a regulating question for all of you.

When a firm is ready to regulate the barrels and actually start to send rounds down range, do they do it by a person (as in a person actually holds and shoots the gun) or is the gun held in a vise of some sort and fired?

Also, on average, how many rounds will a firm throw down range to declare the rifle "regulated"? (If the first two look good, so they stop there or is a minimum of X rounds fired?)

Just curious.
