.50 Beowulf Magazine Classification Update

[RangeBob]

I'm wondering if it will boil down to what Alexander Arms did originally.

Did Alexander Arms
a) take a .223 mag they had lying around, and bend it open with a pair of pliers, eor
b) think: we've been building and designing magazines for years, they have to have this and this and that and that, here's an autocad that will fit our new round, press that out.

If (a) then it's prohibited,
and if (b) then its originally designed as 50 Beowulf and not designed for dual caliber.

That would be my take on it.
