Never used their stuff, but it's supposed to be pretty good. The problem is that any SAA replica (Colt, Vaquero, Uberti, Heritage...) should only be used with the original spec ammo. For .45 Colt, compared to today, that's pretty weak stuff. BB seems to be more for something like a Super Blackhawk or Super Redhawk which is heavy duty.
Oh, there is a difference between the Vaquero and the "New Vaquero"
