Not recommended for auto-loaders or lever action guns, because the shoulders need to be bumped back for reliable operation in those guns. A bolt-action gun has more mechanical advantage when it comes to closing the bolt.
For me, which sizing die to use depends on the caliber. I really like the Redding full-length bushing style sizing dies for bottleneck rifle cartridges, especially for precision loads. Without the bushing, they can be used as body sizing dies. Picking the right bushing will reduce the amount the brass is worked, which will lead to longer brass life.
For any new calibers I pick up, I will probably go with the Redding bushing sizing dies, but I still have a lot of Lee dies (and other brands) that I don't plan on getting rid of.
