Sorry - should have added ... Its a 30 minute time limit - you load within the time limit - comp here http://www.britishpistolclub.org/MLC.HTM
Its about THE commonest BP pistol comp shot ....
The original reason for NOT allowing them I understand - was to stop (a deranged ??) shooter - holding off the Police etc with multiple preloaded cylinders (as if you would choose a BP pistol for this purpose ????)
.... and which comps is it you are going to "muddle" through with one cylinder ?????
Beware - casting becomes a hobby in it's own right - you have been warned !!!!
EDIT : and Reloading becomes a hobby too !!!
Cheers
