Nothing like an evaluation from a consumer who has worked both products. Thanks for posting.
As regards double charged cases: When I shopped for a progressive press I decided to get a five station press so that I could mount a powder check or powder stop die for an extra measure of safety. I ended up buying the Hornady LNL-AP.
Spent a few bucks more for the RCBS Lockout Die. Unlike the RCBS powder check die or Hornady's Powder Cop die, both of which rely on the operator to watch the level of the little rod, the Lockout Die will automatically stop the press if it detects and undercharged or overcharged case. Money well spent in my opinion.
