The RCBS Lube-A-Matic Top Punch 630 (Model R85630) is a precision-machined steel reloading component designed to facilitate the sizing and lubricating of cast lead bullets. This specialized tool guides raw cast bullets nose-first into a sizing die without altering their structural geometry. It is engineered with a custom-contoured face that exactly mirrors the nose profile of the RCBS 25-85-CM bullet, ensuring even pressure distribution across the bullet nose during the downward stroke of a bullet sizer press. Key Features:

• No-Deform Alignment: Features a face precision-machined to match the RCBS 25-85-CM bullet contour, preventing nose flattening, distortion, or misalignment under manual sizing pressure.
• Press Compatibility: Engineered to fit directly into the RCBS Lube-A-Matic Bullet Sizer/Lubricator (including Lube-A-Matic 2) as well as Lyman 450 and 4500 bullet sizing presses.
• All-Steel Construction: Crafted from durable, precision-machined steel to withstand repeated mechanical pressure during high-volume handloading operations.
• Zero Power Requirements: Operates as a purely mechanical tool requiring no electrical power, making it fully compatible with standard manual reloading setups.

Who is the Rcbs Lube-A-Matic Top Punch 630 for?

• Cowboy Action shooters and vintage rifle handloaders — requiring a lightweight 0.05-ounce bullet sizer top punch configured specifically to guide and size .25-caliber, 85-grain (RCBS 25-85-CM) round flat-nose cast bullets without distorting their nose profile.
• Reloaders using RCBS or Lyman sizing presses — seeking a compatible 0.05-ounce bullet sizer top punch that integrates directly with the RCBS Lube-A-Matic 2 or Lyman 4500 manual lubri-sizers to process cast bullets at speeds up to 900 bullets per hour.

Less suitable for: handloaders casting bullets outside the .25-caliber (85-grain) round flat-nose specification, or those utilizing alternative proprietary sizing press configurations like SAECO or Star sizing machines; these users require a different top punch model matching their specific bullet mold dimensions or a proprietary top punch designed for their specific brand of sizing press.
