The RCBS Lube-A-Matic Top Punch #374 (RCBS part no. 82519) is the top punch RCBS’s bullet-casting chart pairs with its 45-230-RN pistol mould. RCBS sells the Lube-A-Matic-2 sizer and lubricator without a die or top punch, so the punch is a separate purchase. The chart lists the 45 Auto 45-230-RN mould with a .452-inch sizer die and this #374 punch. This is the punch number, not a caliber.

Key Specifications

• The punch is the #374 Lube-A-Matic top punch, the number RCBS uses to match punch to bullet.
• RCBS’s chart pairs it with the 45-230-RN mould, the 45 Auto round nose bullet.
• The same chart row calls for a .452-inch sizer die, the sizer diameter RCBS lists for that mould.
• It is an accessory for the Lube-A-Matic-2 bullet sizer and lubricator, which sizes and lubricates cast bullets in one step.
• The die and top punch are sold separately from the Lube-A-Matic-2 press, so the punch is a standalone item.
