After a really weird buying situation, I was finally able to install my Mark 7 1050 autodrive last night. It will be next week before I get a chance to actually load some ammo on it, but I just had to let it run for a few minutes while grinning like crazy. As easy as it is to crank out a lot of ammo fast on the 1050, I'll be really happy to not have to pull the handle anymore.
