I have been reloading pistol rounds (357/44) and rifle except for my ar using the rock chucker for a longtime. The idea of using the rock chucker for doing 45acp and 223 rounds seems tedious to me.
Find a RCBS case kicker which is no longer offered by RCBS. It will dramatically speed up up your Rock Chucker operation.
I have one as well as the Dillon Square Deal B. Case Kicker video :
