I haven't fired my Romy drum yet, but I loaded it with 73, the standard load, and wound it up. Later, I decided to do a static check and manually stripped off 20 rounds to fill a Hungarian magazine. The feeding action was perfect and snappy, and I would not expect any problem in blasting off the whole drum-full. I'll eventually prove the drum at the range (slow single shots by the rules
, then I'll re-load it but not wind it up for storage.
