On the APP it's not a cure for anything. It does some things faster than other methods. The case and bullet feeder is what speeds up the processes.
Many powder coat boolits, this sizes then faster than others by using the feeder.
The case feeder speeds up both decapping and pocket swaging.
It can also do anything any single stage press can do.
A very innovative press.
Onto other things about Lee.
When I first started loading I bought a set of Redding steel dies for 44 S/Mag A friend had a press and showed me how to load. Once I moved out of the barracks I bought an RCBS Rock Chucker Press.
THe R/C is a fine press but has some things I didn't like. The primers didn't all land in the catcher. A lot went on the floor.
The priming happened at the middle of the ram stroke which is not the best place for seating primers. The effort to seat was so much you have a hard time feeling when the primers hit bottom.
I never felt comfortable using primer feed tubes. Perhaps the tubes I had were an issue. When pushing the tube down on the primer they often fell back out. I looked around for a better priming system and found the Lee Hand Prime Tool. It was much better than on the R/C.
When operating the press I didn't like the mushy feel as the press cammed over. It didn't feel very precise. It took a bit of fiddling when setting dies. You couldn't just raise the ram and thread a die to touch the shell holder. If you did you might not be able to lower the ram. You had to back the die out till you could. It work as is but never felt right.
In a move I lost my loading equipment. When I got settled I bought a Lee Loader press an 44 S/Mag die set to get started again. I liked the little press but I felt I needed an O frame press. I bought the Lee Challenger and started to use it I liked the way the ram came to a stop at the top of the stroke. This has a solid precise feel to it. This made setting dies quicker and easier. .
To prime on the press I tried it by hand feeding primers in the arm. This was not bad. The priming happens at the bottom of the stroke. This gives better feel of when the primer bottoms in the pocket. I prime off the press so never bought a primer feed for the Challenger.
With the way primers fall after they get punched out of the case isn't perfect but very few primers don't go down the chute into the tube. Much cleaner than the R/C or any other press I had used up to that time.
My Challenger uses the breech lock bushings. I just leave one in the press and thread dies in/out. The time it takes is not that much.
I think if I had an R/C on the bench next to the Challenger I wouldn't use the R/C.
Other press I have used are an od CH C press, Lyman Tru Line JR, RCBS R/C, The Lee Loader and the Lee Challenger.
Not as many as some others have but I feel this gives a good idea of how other brand handle these tasks I've talked about.
Some don't think the alloy frames Lee uses are strong enough. For most things most loaders do with a press Alloy is just fine. It may not be as massive or heavy a press but moist don't need that.
The alloy frame doesn't flex as much as cast. How this affects most loaders is questionable .
There are other design features Lee uses that make their press unique. The adjustable length handle. When not needing it's full power you can shorten it so you have less arm movement.
Being able to swap the handle from right to left is good also.
Some of these features are now being incorporated into other brands of press. The same thing applies to other products Lee make.
I guess I've rambled on long enough for now.
