Looks good Sir Ron, thank you. ONe of the reasons I got out of precision rifle reloading was that I hated the case prep. It didn't help that I needed thousands of rds a year. I think the 458 will be much more manageable, and hopefully even fun to mess with those big cases. I have a Lee trimming system, which I will try out and then go from there if it doesn't work well enough. As an aside, though I'm. bit of a Redding snob in many ways, I have found most of the Lee stuff to work as advertised and have been very happy with those purchases. Just depends what you are trying to accomplish.
