38 posts, and the OP hasn't replied yet. Oh well, great discussion anyway!
A couple considerations:
1. The hornady lock-n-load bushing system is great! you can get it by ordering the Hornady Lock-N-Load classic single stage, or add an upgrade kit to other presses (lee classic cast for instance). Why unscrew dies when you can pop them in/out in a second?
Hey UR, did you ever do a video of the Lee classic cast? The quality of your videos are outstanding, I'd like to see one of the Lee classic cast?
The LNL bushing is a solution to a problem that doesn't exist! Same with the lee breech lock. Why some find it so hard to screw a die into a press is beyond me. If you're in such a hurry, you're breaking one of the basic rules of handloading, take you time! Once a die is screwed in and adjusted, the lock ring locked, it doesn't need to be moved, it stays adjusted. The only die that needs to be adjusted is if you need to vary the crimp on a seating die. Then, you'd still need to do that even with the LNL bushing! Do the LNL presses have a standard 7/8-14 adapter so you could eliminate the LNL bushing?
I also have a lee classic turret. I find myself using that more than my dillon 650. Mainly for load development, which is hard to do on a progressive. The CT is a fine machine capable of some pretty good speed,(output). The CT cost about what one caliber change costs for the dillon!
Oh, also, the Lee classic cast has the ability to add the Lee safety primer feed. The top of the press has 2 threaded holes to fasten it to the press. I haven't tried it yet, maybe today?!
