I'm a fairly low volume reloader now too, about 100-200rds per month average, mostly rifle, so I still do things the old-fashioned manual way.
Not many powered tools on my bench except for the case trimmer (read #3 below).
I used to load upwards of 1000-1500rds per month when I was a bit more active with my handgun shooting but I still used the same setup. It's a nice slow relaxing activity for me...I enjoy reloading as much as I do shooting the ammo.
Some guys prefer to zip their reloading out as fast as they can though, and those guys usually have more power tools and/or progressive presses too.
You've got a nice wish list put together and it will serve you nicely.
I'll offer up a few suggested revisions going on my methods though.
1. The RCBS Rangemaster 750 Scale.
I would suggest that you look at the PACT brand scales. They are identical to the RCBS counterparts (PACT makes the RCBS digital scales) but without the extra pricetag associated with the green color.
I would also suggest moving up from the Rangemaster750 (aka PACT BBK2) to the the PACT Precision (aka RCBS Chargemaster1500) model.
The PACT Precision is only about $20 higher than the RCBS version of the BBK2 and you get a better scale out of the deal.
The Precision/1500 offers a larger total weight capacity (which you probably won't use that often as a beginning reloader) and also a more stable base and a more consistent load-cell configuration (which means that you will have to recalibrate/rezero the scale less often).
2. The TrimMate prep center.
I still do my case prep manually so I think you could save a few dollars by holding off on the TrimMate prep center. It is a nice luxury but for a low volume reloader you could either save that $100 or invest it into other goodies to begin with
You can substitute:
-A manual deburr/chamfer tool to clean up after trimming the cases.
I don't like the Lee style...go for an RCBS, Hornady, Wilson, Forster, etc instead they are more comfortable to hang onto than the stubby little Lee version.
-I also just use a small 1/8" pocket screw driver to clean the primer pockets. One quick twist is all you need to scrape the primer residue.
There are manual primer pocket brushes, but I started out cheap with that pocket screwdriver and I'm still using it 20+ years later.
-One of the manual case neck lube brush sets. These come with several size brushes to cover several calibers. I have the Frankford Arsenal version but the Lyman and Forster sets are about the same. All they are is a holder for a nylon brush and some powdered mica.
3. The RCBS trimmer.
This is a very good trimmer unit. I do like it. The universal shellholder with the paddle handle is easy to use.
But if you're loading just a small number of calibers I would suggest looking at the Lee stud and cutter trimming system. You can get set up for one caliber for about $15 and each additional caliber stud is around $5.
Another advantage to the Lee system is that you can chuck the case holder into a cordless drill/screwdriver and viola, it's a power trimmer.
Everyone develops their own system of what works best for them and I'm sure you'll do the same.
Do you have any local buddies to help mentor you as you get started? If so, that's great to have an extra set of eyes as you crank out your first few rounds. But if not, be sure to keep hanging around this place. Lots of great folks to help ya out!
