AOW

There use to be pictures of an ATF letter saying so. Fuck PB...

semi related question, what is the correct name for "dust buster rounds"? the iron filings one that are used to break locks because of the low chance of ricochet

>>34978270
Breaching rounds?

>>34978284
thats it, thanks

>>34978270
>because of the low chance of ricochet
breacher rounds use tungsten powder because they transfer energy more effectively at shorter distances than other forms of ammunition and lack the potential to penetrate significantly - which often seizes the lock or risks injury to breachers from fragmentation (spalling) of the metal lockwork breaking.

ricochets have nothing to do with it.

You think that making those wax slug type rounds would similarly work because of the physics that >>34978307 explains?

>>34976950
Neither

SHALL NOT BE INFRINGED

Aside from breaching, wtf is a masterkey even useful for?

>>34979619
It's not.

Why do you think it's called a masterkey?

>>34976950
I'm curious; what keeps it from being an SBS? It's short barreled, it's a shotgun. So how come it comes in as an AOW?

>>34979670
That's what I thought. They look cool, but I can always get a nice sledge for $30 and not add 5lbs of dead weight to my rifle.

>>34979676
It's not a shotgun unless it is designed to be fired from the shoulder. Yeah, it's retarded.

>>34976982
reeeeeeeeee so much of the internet is lost to bit rot due to forums exclusively using photobucket from the mid 2000s until fairly recently. this is LITERALLY rape.

>>34979724
Wait - if I was to build a real-life Force-a-Nature ultra-sawn-off, it'd be okay?

>>34979724
Won't it become an SBS when you attach it to a rifle that has a stock?
