I don't like it better than the adaptors. I love the speed and ease of the adaptors, but they don;t work in the Classic Cast. Since I like using the Classic Cast press so much, I no longer need the adaptors.
In other threads on other forums, I've said that IF I could re-design the Classic Cast press, I would make a three-tier mounting system for it: At its largest, it would handle the .50BMG and other large dies, then it would have a medium-sized opening to handle the quick-change adaptors, and finally the standard 7-14 opening for regular dies.
In your case, I wouldn;t bother trying to "change" the Franklin press, just get a Breechlock Challenger. While not as heavy duty as say a Rock Chucker or Lock-n-Load, and definitely not as solid and beastly as the Classic Cast, it's still a fine press and will load whatever you want.
Or even better yet!!!: think about a Lee Classic Turret press. It won;t use the adaptors, but it does handle the four-hole die sets. The dies stay set-up and adjusted all the time and the only time you have to change it is to change calibers, and then they too are set-up and ready to go by just popping in the 4-hole die bracket. Plus, you get the massiveness of the Classic Cast in a turret press............
