Powder measure/thrower?
Powder scale?

Primer pocket cleaning tool?
Primer pocket decrimp tool (if using military .223 brass)?

Would not get a rotary tumbler, just takes too long. Highly recommend the standard vibratory tumbler. HF's is about $20 more expensive than the Frankfort Arsenal one that Midway, Sportsmans, etc carries.

I love 2520 for .223, but I am out of it atm.
