Just finished pulling bullets, and dumping powder on the last of the 150 loaded rounds that came with my Sharps! My kinetic puller isn't large enough diameter to handle the base and rim diameter of the big .50, so had to scratch my head to come up with a solution. I found in my nut and bolt bins a 1/2" washer that was just large enough for the cartridges to slide down to the rim. I took the collet out of the bullet puller, and screwed the threaded cap back on. Then just dropped the cartridge and washer onto the puller. It had just enough friction to drag on the case diameter, and keep it from popping out during the hammering process. (most the time!) I did have a couple cases that went flying when the hammer hit my vise, but didn't go far.
I tried a few empty cases here and there to see if any primers went bang, but none did. So next they'll get deprimed and then work up new loads for the Sharps.
Had the set trigger screw fail on my Gove underlever Rolling Block at the same shoot. It stopped setting, and when I tried to adjust the screw the head broke off! Fortunately the threads stayed with the head, and just the tiny tip broke. It had rusted into the trigger, and so badly I had to drill the pin out to be able to punch it. Have a new adjustment screw coming from Numrich, so should be fixed before I want to shoot it again. I kept shooting after it broke, just unset. It's about 4 lbs. when not set vs. ounces once it's set.
