I leave many(most) in the die boxes and if I find a set of dies I can use with the shell holder in the box...I buy them. At most shows they sell for 20 dollars or less. Shellholders new these days are 10 bucks. at the last auction I bought a set of RCBS carbide dies for 32 S&W L H&R mag and 327 Federal with the shellholder and a cal conversion shell plate with powder funnel for a Dillon 550 for 40 bucks. Nothing looks used
