I use it in my rock chucker supreme - you can see it in my pic above. Your older rock chucker should work as long as you have a threaded bushing in your press
. I don't know if the older ones did or not, but now just about all presses do. You should be able to tell easily if you look at the threads on your press. If they're mahined directly into the green cast metal, it won't work. If you have a steel hex bushing with threads in it, then it should work. You have to muscle that bushing out of your press with a big pipe wrench and replace it with the one from the kit.
As far as the regular ring system being a pain, it is for me. When you use a normal lock ring on your dies, it not only sets the depth of your dies but it also creates the torque that keeps the die in place on the press. When you have to switch out a die, I'd often have to take a wrench to the lock ring, and the lock ring would invaribly move, which for me caused way too much variance when I'd put the die back for my next round.
The Hornady setup has locking lugs like the bolt on an ar-15, so you drop the die/bushing in and in 1/8 twist it's locked in place. The die lock ring maintains its interface with the die bushing and so the die seat depth never changes.
I loaded my first several thousand rounds without the Lock-n-Load bushing setup, and I lament all the wasted time I spent adjusting die depth before I figured out how well the bushing setup works.
