Hey Ya'll,
I've worked with one of Dr. R.G. Gatling's revolving battery guns.... The cartridges were load into 'chambers'. An iron cylinder with a musket cap and nipple on one end and open to .58 on the other. The 'chambers' were preloaded with 150 gns ( yup that's right 150 gns ) of musket powder and packed in tins. When the battery gun was in position the chambers were fed into a hopper on top of the receiver. As the handle was cranked the chambers went through the mechanical cycle and were then collected by the crew to be reloaded.. Rates of fire up to 650 rpm have been documented..
TWIMC.. the battery gun I helped with was an original and it was used in the draft riots in new york and by ben ( the beast ) butler at Bermuda's Hundred in Virginia...
Stay safe
