There are lots of ways to trim cases fast. But only a few of the pricier options will trim and chamfer at the same time. And you'll need a unique, pricey cutting head for each caliber.
OTOH, one of the cheapest options will facilitate motorized trimmer, chamfering, and even case polishing. The Lee Zip trim chuck takes longer to put each case in than using something like a Possum Hollow, for instance. But because it rotates the case, you don't have to hold each cartridge with a death grip, like with the Possum Hollow type tools. And after you trim, you can stick the chamfer tool on the neck and give another quick spin and even polish the case before you chuck up the next one. (With a Possum Hollow, you'd either batch process trim and chamfer in separate steps, or you'd have two drills setup, or you'd chamfer each one manually after trimming.)
I plan on starting to load for my 30.06, 30/30 also, but I may get a possum hollow trimmer for them since it will be a much lower volume.
That's one of the great things about the Lee trim setup. For each different caliber, all you need is a 5.00 guide. The same cutter, chuck, and chamfer tool will work for all your calibers. So until you get up to the trim/chamfer combo tools, the Lee system has some unique benefits that partially offset the time spent on chucking up the brass. I like it. I also like not having to readjust the depth stop each time I change calibers. Just screw in the appropriate guide, and you're ready to go. Extra cutters are only 5-6 bucks each, so you could even lock tite the guide in there and have one for each caliber. I imagine I'll always have a Lee cutter, no matter what other brand I own, such as my Wilson. It's cheap to buy a Lee guide when you want to play around with a new caliber.
