Many moons ago I found a middle aged woman selling a bunch of military surplus. While buying a pistol belt/canteen/cup combo, I noticed four white boxes. Opening one up I found the Item in the title. It came with the clip loader and a parked steel pusher rod. I asked what she wanted for it. TWENTY BUCKS EACH! Ran back to the ATM and bought them all. Upon inspection, I could tell these drums were not meant to be kept loaded. The first sixty loaded easy enough, but the last thirty practically had to be loaded one at a time. Using my early Colt A2, they fed well when loaded to 75 rds, sometimes sluggish feeding with a dirty gun with 90 rounds. That Colt was sweet, never shot worse than 4 moa even with my no-name bullet crap handloads(55 gr bent and pulled SP, 25 gr BLC-2, Win SR primers, mixed brass). I miss that rifle. Still have the drums. Anybody else had experiences with them?
