How bad is case forming? If there isn't much to be gained with the 30 American over the Ham'r then getting factory ammo and skipping the case forming is tempting. I would think a guy should be able to resize standard 6.8 cases, trim to length and load 'em from what I see. I'm surprised Hornady hasn't come out with this as a factory offering.
I'm not sure about the 30 American, but that's pretty much what I do with my very similar wildcat.
For "drop them on the spot" performance, I think you'd be pretty happy with the results of the 125 NBT.
