Raises another question. Ever wonder why a new gun comes with a spent

To test functionality. And/Or, to build a database of gun "fingerprints", i.e. bullet striations. That info, along with registration, can lead back to the owner.

I have never bought a gun with a case in the box.
I do question the validity of all of these ballistic fingerprint
things if the gun has been used a lot. I agree that if they have the
gun and a recently fired bullet or case, they usually can match them
up but if this gun has several thousand rounds of barrel erosion and
the slings and arrows of dirty ammo going through it, matching up
tool marks from the day it was made is going to be far from exact.

I bet the difference between S/N xxxxx1 and xxxxx2 brand new is less
than xxxx1 to xxxx1 after years of hard use. If the same tool cut the
rifling, won't the tool marks be very close to the same?

Interesting. When was the last time you bought a new gun?

Every gun I have purchased in the past 3-4 years has an envelope with a
spent round casing that was fired from the gun at the factory.

It's also mandatory that new guns come with some type of lock.

Is this a MA thing or is it true everywhere?
