I have a 6mm-06 wildcat. I have a set of redding custom dies that I use. I generally trim 270 brass and resize it.

Pavomesa is correct, it is easy to end up with grease dents, but they fireform out.

My 6mm-06 is built on a rem 721 action, montana 28" barrel, timney trigger, boyds jrs stock, leupold bases and rings, and a burris ffII 4.5-14x44 scope.
