Energy is unhelpful on ranges, as a .50 cal BP at full stoke will have a very high energy, but losses it very rapidly compared to a .308 for example.
I believe that .357 carbine should be permitted (if we consider it to be a c/f pistol calibre) as the max. permitted is .44. The stipulations regarding MV/ME are in the range safety certificate, so MV will have to be measured to ensure that neither criterion is exceeded.
