Trimming in volume
I detest trimming and have bought an X-die that will hopefully eliminate most of it, however before used in the x-die brass has to be trimmed to .010" less than minimum. The 223 cases here were a little over maximum so I cut off a lot of brass for this trim. I set up my trusty stopwatch and did 80, then divided it out and came up with 10 every .94 minutes. That is trimmed, chamferred, and de-burred. The only other trimmers I know of that can approach this speed are the gracey and giraud but they are expensive.
My method uses an RCBS manual trimmer with the handle removed and a battery drill chucked over the shaft, a 3-way cutter head, and aluminum foil to catch some of the brass, I use a lot more reynolds rap now, it flies all over the place.

Interesting way to speed up a slow and monotonous process. I may look into doing something like that.

Re: Trimming in volume
I know you talked about them, but if you plan to process a lot of brass or often, consider getting a Giraud Trimmer. It trims and champhers brass at the same time. You can also change out to other calibers.
I also used the drill method, but when you are processing a lot of brass, to me it got to be a chore having to charge and change out batteries, etc.
Girauds are not cheap, but if you decide to sell it, you can almost always get most of your money back.

what calibers do you need to trim? I can bring the Giraud to the range and you can trim lots of brass quickly. Set up for .223, 308 and couple others..

Re: Trimming in volume
I used a giraud to trim 50bmg brass and it was amazing.
I use a dillon trimmer for 223, 308, and 30-06. But i dont ever debur them for blasting loads. I use a zip trim and lee case trimmer for my "match" ammo.
