True, but I think they have too much spread. Just my opinion and yes volley fire with buck and ball can be devastating. We did test it on single fire at the range and that's what my comment was based on.
I think that's the hangup here- people are thinking of the individual musket's accuracy, which isn't how it's supposed to be used. In the role it's designed for (massed volley fire at mid-range enemy lines) the 1842 is devastating.
