I'll take a stab at Green Mountain.

I'll take another stab and say 008 is rifling depth in inches.

those GM barrels are terrible! i could be talked into taking that jack handle off your hands!
I have a .50 with the "70" twist. actually 68" but what's 2 inches between friends.
have been using GM barrels for years and am very fond of them.

Good to know !
Just been trying to figure out this “Frankenfowler” I lucked into awhile back ! Seems it’s a Jim Chambers Virginia Lock and now I know a Green mountain barrel !
And I’m alright with that
