I started reloading on a Dillon 450 many years ago. Never had a single stage press. Still don't. Upgraded to 550, used it for 20 years. Sold it for more than I paid for it.

Went to 650. When you learn how to "OPERATE" your press properly you will turn out substantial volumes of reloads easily....with no glitches and a bunch of primer tubes ready, 600-800/hour is comfortable.

This gives plenty of time to clean, change primer sizes, etc.

You learn how to do batches....same size primers but change tool heads, takes a few minutes, including shell plate. If you have the spare dedicated powder measures, they are already preset if you use the same powder.

If you need a single stage press feature, you can always use that portion of your 650 for whichever function you want.

I've loaded 45-70, black powder, and a number of rifle rounds as a really efficient single stage, simply because I didn't have all the components for that particular type of progressive set-up.

Caliber change over typically can be spendy:

I prefer Dillon dies--typically ~$70 range; tool head ~23; conversion set up ~73; and if I'm using the Lee Factory Crimp Die as a chaser in Station #5 there's never an issue with such as the famed Glock bulge on range brass.

The auditory set up for powder charge is certainly a most worthy component to add.

Without the case feeder you are wasting your time.

And yes, I'm voting for the 650 as it does all pistol & rifle calibers, using standard dies.

Loading with a 650 compared to a single stage press is like shooting an M5 compared to a muzzle loader....no disrespect intended, just totally devices...
