    I have a set of redding s type bushing dies for 300 ultra. Can I use these dies for 375 ultra if I get a different bushing for resizing? Will the 375 brass /bullets work in the seater die?

    I would doubt it generally ur bushing dies have the shoulder as part of the die and not the bushing. I mean u could make it work if u softened it and machined it then rehardened it but it would be easier to get a different die set

    It's essentially the same case with a larger neck diameter.

    So, the question is whether or not the diameter of the die just ahead of the bushing has sufficient clearance.

    From what I can see without disassembling one of my redding dies, the orifice is only a hair larger than the bushing ID.

    You can remove the bushing and see if a 375 case will clear the orifice.
