Brass preparation is my least favorite thing ever. I'd rather take a shot to the nards, eat Brussel sprouts, parsnips or kale than do brass prep, but it's a necessary evil that must be done.
Silky, I think if I were you, I would invest in a better trimmer first. Nothing fancy, like a Forster, would do the trick. Like you I end up doing sometimes THOUSANDS of pieces of brass. As I'm Scottish (therefore "Scotch") I am tighter with a penny than any Jew (Shalom and no offence intended) my time is worth little when it's mine to spend. I have a routine and when I get in that routine I can trim, chamfer, deburr and prime 150-200 pieces of .223 brass an hour with no help from outside power sources. I have, in the past, done 1000 pieces (separated between four different rifles) in a day. Now that my hands are "slower" I follow through the loading process to the end and load for one rifle per day. I might only have 3-400, but that's what I'll turn out before it becomes too tedious.
Anyways, I'm not you and I was just "regaling" a story.
