RCBS ChargeMaster Combo. You won't wind up with a beam scale and powder measure, trickler, etc. that you don't need.
Calibration Weight Set.
Wilson case trimmer with Sinclair base (obtained as a unit from Sinclair). Get caseholders for fired cases (new cases typically don't require trimming).
Redding and Forster dies. Forster's non-mic seating die is preferred to Redding's standard seater.
VLD chamfer tool (Lyman, RCBS).
Imperial Sizing Wax.
Sinclair has great accessories. The Satern aluminum funnels are really nice, as are Sinclair's loading blocks, concentricity gauge, primer pocket tools....
You'll also need a priming tool. RCBS's Universal and Lee's AutoPrime hand tools are popular.
