Put a piece of foam in the bottom to save the bullets from damage and toss the powder into a container to reuse. Not that big of a deal really. I also have collet pullers but sometimes, they dont get a good enough grip and are about next to useless on cast bullets. I wind up using my whack-a-mole puller most of the time. The only impact puller that didn't work for me is the all plastic RCBS one. I snapped the handle off of 2 of those on the first hit. The FA puller has worked well for me.
