One thing I've wondered a while now about SXS guns is why the firing order is the way it is. I get the concept of having chokes of varying constrictions, but it just seems sort of backwards to me to fire right then left. I've always found that while the right barrel feels softer to shoot, the muzzles are pulled farther off target because of the recoil than the left, which is the opposite. In my mind it makes more sense to have the left side fire first, because it's faster to recover from the recoil on that side.

Is there any specific reason for a R/L firing order as opposed to L/R, or is it just a case of things having been done that way since the inception of the double gun and never being altered?
