Yep, I used the Clear shot or Clean shot whatever it is called. Nearly filled the case and added a 50cal Lee REAL bullet that had been lubed with liquid alox. That was a fun round. Might have worked better if I had used a sizer on it. It kind of has a tapered shape so I seated it long and forced the action closed. If I seated it to a shorter COL it made the case too fat to chamber with thumb pressure. It was a soft lead and worked well if I left it long and let it ride into the rifling when I chambered it. I didn't chrony it, but it was fun to shoot. Off hand at 25 yds and peep sight was good enough for pop cans. I can't remember how much powder it would hold. I might still have a case laying around to check, unless somebody beats me to it.
