Had an original that stripped out the die lock ring threads and returned it to RCBS for repair and instead they sent me a LAM II as a replacement. Sturdy as all get out but refilling the reservoir is a real PITA compared to the older model (or Lyman 450). The reservoir cap is threaded and needs a 1 3/8 wrench to remove. In addition the die lock ring is 15/16, fortunately have several wrenches in my toolbox. Was hoping RCBS had a combo tool (ALA Lyman) that fit these nuts but can't find one on their web site. What are other forum members using for the LAM II?
