I'm running a 1050 with Mark VII Autodrive. I must have loaded north of 150K rounds with this setup. Recently developed severe powder leakage and upon disassembly found a large crack in the body. I suspect this crack had been developing for some time since I found myself having the fiddle with the height of the die over the last several weeks. When I reassembled with a new die body I had to dramatically raised the powder measure. The 1050 isn't under warranty, but the part was $50 with shipping and arrived very quickly.
