I do mine in a very similar manner except I have a Wilson trimmer.
I use a Sinclair adapter to hold a standard camfer/debur tool in my cordless drill. That makes the post trimming cleanup fast too.
Plain old prehistoric Forster with hand crank. I do have the power-driver adapter for larger lots of brass, but more often than not I just Go Stone Age. 95% of my case trimming involves jacketed bullets in gas or bolt rifles; cast bullet loads seldom need that sort of attention. Exceptions are the 32/20 WCF and 44/40 WCF, esp. with W-W or R-P brass. These will tweak if looked at intently, and stretch every firing. They require a trim every other firing. Starline is better-behaved.
Same as Waco, except different brand of drill. Don't have the drill adapter so I just screw on a 5/16 nut and use a socket with adapter in the drill. Picked up over 200 Frontier brand 5.56 cases at the range late yesterday afternoon. Got them through the tumbler, sizer and wiped down. This morning setup the trimmer and cut them to standard 223 size, 1.75", deburred and reamed the primer crimp. Weighed a few and they matched some Hornady commercial I had so should make some good brass for predator hunting.
Forster with hand crank for me too. For .308 I recently upgraded to their single-point cutting head that does inside and outside chamfering at the same time as trimming, took about 47 hours to get all three cutters adjusted to give the amount of chamfer inside and outside that I wanted, but after that it's easy. I'll buy another cutter head at something like $50 IIRC before re-adjusting this one for .30-30.
I used to clean up the high spots on my necks during the initial trim with the Forster but I'm losing interest in sub-MOA precision shooting and am much happier with quick'n'dirty methods now. I may get a Giraud or WFT at some point because they would do exactly what I need, and fast.
I use the Forester hand crank, also.
Like Ole 270, added a 5/16" nut and use a batt. operated drill for large batches or when cutting down brass for a wildcat.
I use a forester also,,,,,,,, yea slow & I have to be in the mood to do a pile of brass with it, the worst was doing 219 zipper from 25/35 brass. When the 25/35 comes out off the zipper die it is quit long<< lots of grinding there.
I have the RCBS hand crank trimmer for straight wall cases - the Lee cartridge specific trimmers for a lot of my bottleneck rifle cases - and the Frankford Arsenal case trim and prep center, for high volume bottleneck case prep (.223 and .308).
