RCBS Rock Chucker Supreme here. 300WM, 338 Lapua, 270 Win, 40 S&W, 44 Mag, 45 ACP and of course 5.56.
I agree, the RCBS bench priming tool is the best I have found so far. I am pretty sure it will out last me, but that isn't saying much.I use an RCBS single stage press with LEE and RCBS dies.
I enjoy reloading, and I am not in a hurry. I reload 9mm, 45 ACP, 38/357, 32/327, and 308/7.62.
I have to say that my recent purchase of the RCBS bench primer loader was a wise decision.
