I was looking at some BP rifles and revolvers online. I see some big bore calibres, but others that would be close to some centrefire cartridges used today.
And so I was wondering how the ballistics of BP firearms actually compare to centrefire cartridges.
For example, I was looking at rather an attractive 18" revolving carbine in .44 cal.
The .454 roundballs for that are probably about 150gn perhaps, then there is online velocity quoted at about 950fps.
Which calibres could be said to have the same/similar ballistic profile?
