I've herd some bad things about molly bullets pitting barrel? You may want to look into that.
As far as a press goes I have 3 The Lee that came with my kit and 2 Rock Chuckers. If you have semimi auto pistol you will want progressiveve press. You wont "have" to have one (don'tnt) but It'd be nice for pistol ammo.
I haven't used the Hornady press but it looks nice. On my dies I use the lock rings with allen screws on them so once the die is screwed into the press it's ready to go. That makes the set up pretty easy.
As far as cleaning the cases My Uncle was a Benchrest shooter & he almost never cleaned the cases? Me on the other hand, I can't honestly remember a case I didn't clean.
Hey rockchalk06, What do you use to lube your cases? I use the spray on stuff.
