If you're looking to save time, in both case prep and loading, I'd suggest the following:
- Dillon XL650 with case feeder
- Dillon RT1200 trimmer
- Lyman 30L M die
- Universal decap die
- Re-use your existing FL size and seat dies
For case prep, you dump cleaned, lubed, fired cases in the case feeder, and spit out deprimed, resized, trimmed, and neck-expanded brass, ready to load.
After another quick run through the tumbler, to clean off the lube, you put the cases back in the case feeder, switching out the tool head with one set up with a universal decapper, the powder measure, and a seat die. The decapper cleans the flash hole of any remaining media, the rest of the press does it's thing, and you spit out completed rounds.
For even more output, add a bullet feeder to the loading tool head, and you're about as automated as you can (reasonably) get. You'll be in to the equipment for about $1,200 (press, case feeder, trimmer, trim/size die, extra toolhead). Add another $500 for a bullet feeder. You'll prep an easy 1,200 cases in an hour, and load 600 an hour, or close to 900 per hour with a bullet feeder.
