DerbyDude, the powder capacity for for all cases is basically the same. It is like up the charge in a 30-06 case and increases the pressure from the SAAMI max of 60,000 psi to 55 or 70 thousand psi this will crease the velocity.
Derby Dude the only reason the Rowland case is longer is to prevent clambering in unaltered pistols. If the Rowland case can be shortened to 45 ACP length and the same power loads can still be assembled.
