If you are a handloader hacking the barrel off, whatever the reason, may be an interesting project up to certain limits. The case capacity is about 95gr H2O; you need to consider burn rate vs barrel length the goal being meet or exceed 100% of powder burn nefore the projectile leave the muzzle; meaning the shorter the barrel the hotter the powder, otherwise you end up blowing unburned powder out the end, does make a pretty fireball though.
Actually it's best to be some percentage more than 100% because it isn't the amount of powder burnt that propels the projectile, it's the expanding gas produced by the burn so you need the barrel to contain those gases.
