Oh wow, thank you for explaining how guns work. You’re so smart!

It’s weird that my guns never destroy the brass. Does that mean they don’t work?

And I guess C4 isn’t an explosive either, because it burns slowly?

And I never said anything about the receiver. The chamber is a different part. And the cartridge will absolutely build up pressure before the bullet has time to leave.

Is your firearm knowledge just based on YouTube?
