My experience with MK 7 is a nightmare, I purchased a Revolution and received it 20 days ago so far we are at 30 phone calls, and 27 minute video chat with a tech. I also sent eight videos of it messing up and spent two days doing what they asked me to try because they had no idea what the problem was. When the machine came in the shell plate would not turn so I had to dissemble the the upper half and adjust the indexing paw to turn the shell plate after that was accomplished the primer disc would not index as well so we had to adjust the ram travel. Now I think I am ready to load ammo but the powder thrower is intermittent so some cases get powder and others don’t, it was to come with a powder check die but was not shipped and I was not informed it was on backorder until I had to call and ask where it was. Now I am being told the parts I need to fix the machine are not available. We will not even get into the problems with the primer flipper. Keep in mind we are talking about a $11,000 machine.
