Power case trimmer for straight wall cartridges?

[Doc Holloman]

Does anyone make a power case trimmer for straight wall cartridges like .45-70, .38-55, .357?  Every one I have looked at only works for necked cases.

LEE Presicion makes trimmer-kits that you attach to a power drill.
I've found that these work for both straight wall and bottleneck cartridges.
In my experience .45-70 and .38-55 won't stretch sufficiently to warrant trimming...
