I had to order one of the new dies for my .44 DDPP to get the base down to .444" so it fits in the case mouth of my tight chamber .44-77.
I use a RCBS Rockchucker and took the 1-1/4 bushing out and screwed their adapter in. It works just fine but I like the old 7/8X14 dies better.
But I won't spend the money for their special stamp metal press they came out with.
