@jacky, I have a Dillon 650, in theory I use it to load .45 ACP, .223, .30-06 and .308. In reality I load perhaps 500 rounds of .45 ACP per decade; I mostly use it to load high-precision .308 target ammo, perhaps 2000 rounds a year.
For the quantities you mention, you don't _need_ a progressive press, but I would be the last person to tell you that you shouldn't buy a nice piece of shooting gear that you'd like to have.
One thing about a progressive press is that it is *much* slower than a single stage to change over for a different cartridge, when the other cartridge is of a different "family" - for example, large vs. small primers, or a different shellholder size, or a different case length.
To change from .308 to .30-06 on my XL650 takes about 20 seconds (I take out the .308 toolhead, I insert the .30-06 toolhead). Nothing else needs to be changed, since they use the same size primers and they use the same size shellholders.
To change from .308 to .45 ACP takes me about 90 seconds. There's no need to change shellholders or primer system, but I do need to change the feed plate in the case feeder, and a couple of plastic bushings in the case feeder system.
To change from .308 to .223 takes about 10 minutes. The shellholder has to be changed, and so does the primer system.
In your case, the three calibers you mention all use different size shellholders, so you're looking at a 5-10 minute job to change between calibers.
If I were you I might buy a progressive and just use it for 9mm (running a progressive to make pistol ammo, on a well set up press, is a *lot* of fun...!), and continue to load your rifle ammo on a single stage. For those quantities of rifle ammo it would probably be faster to do them on a single stage than on a progressive.
