It doesn't sound like you have hit that wall of "dang it this single stage press is SLOW!!!!" quite yet. Nope not quite there yet.
I just want to make sure you don't focus too hard on the volume and miss other options.
How hard is it to change out to a different caliber?My 2 main calibers are 45 ACP and 38 Special, both of these are set-up on my Redding T7 Turret. I added the Hornady quick change bushing to my RockChucker II for reloading my rifle rounds, which makes changing over dies quicker. Shoot only a couple hundred rifle rounds per year. Does Dillon offer a 25-35 WCF caliber conversion?
How is the priming done? RCBS Automatic Bench Primer
How is maintenance done? I lube the rams. Clean off any priming debris.
What upgrades are available? Piggyback is obtainable, but I can't validate price versus effectiveness. No offense to anyone running the Piggyback option on RockChucker's, Just the last few Piggyback conversions I have seen sell for over a couple hundred.
If you get too wrapped up in just how much does this one load then you miss a lot. I mean the Dillon 1050 is the fastest thing I know of with the most options built in but that final question is:
How much am I willing to invest? Excellent question, as I think this would go hand-in-hand with the question I posed.
