Trimming cases for Wildcats. Everybody's got a way...

I use a Dremel Drill Press. It's the fastest way I've found to trim cases with a factory smooth cut.

Set the cutting blade above the base plate just a tad higher/longer than you want the case. Sit the case on the plate and rotate 360° with two fingers.

I use this for 300 GNR, 500X1.4", 458 D-MAX, etc.

Not the best pictures, but everyone will get the idea. Just trim to final length, chamfer and load.
