Great thread and comments!

The Hornady L-n-L conversion bushing is, IMHO, an absolute must for single stage presses like my LEE Classic Cast Iron press: once adjusted, dies are good to go, easy to make small adjustments for seating depth and crimp. Perfect for rifle rounds, especially bottle-neck cartridges. Even the LEE locking rings stay in place... Well, most of the time?
Absolutely love the RCBS Universal Hand Primer: easiest way to seat primers properly whilst watching the tube, just remember to always wear your safety glasses, just in case...
LEE's Classic Turret won't accept the L-n-L system, but that's the point: you buy another turret, adjust the dies once and away you go. Batch loading (i.e., say 50 at a time per loading "action" & removing the indexing rod) really can up your production with no real decrease in precision. No doubt (in my mind) a Dillon or a total Hornady L-n-L Progressive system properly set-up, adjusted and maintained can deliver many more finished product much faster, but at what co$t? How many actually shoot 500-1000 rounds per week and really need the production?
If you are one of those "lucky ones", God Bless and Keep Safe!
Cheers!
p.s. Easy for me to say because I'm retired and actually think the reloading bench is the perfect place to be O/C and proud of it!
p.p.s. Found an old RCBS Jr. at a garage sale for $10 to handle all the decapping chores: SAVE THE DIES! With the LEE quick change mount it's only a minute's work to go from decapping to single stage or turret press. Hint: replace those Phillip's head screws with hex head bolts for a tighter mounting.
