I currently only load shotshells on both a single stage and progressive press. I'm considering the RCBS Rock Chucker Supreme Master Kit from Cabelas to start reloading metalics. I wants to start with .45 ACP, 38/357, and 3006. I'll expand later. The kit is $249.99 from Cabelas and comes with: RC Supreme Press 5-0-5 Powder Scale Uniflow Powder Measure Speer No. 14 Reloading Manual Hand Priming Tool Hex Key Set Case Loading Block Case Lube Kit Powder Funnel and Deburring Tool. So what else MUST I get to get started and what else to buy later will make the process easier? Thanks.
