Lyman H&I Bullet Sizing Die, .451-inch

The Lyman H&I Bullet Sizing Die in .451-inch diameter (Lyman part no. 2766515) resizes cast or swaged bullets to a precise, uniform .451-inch diameter before they go into a case. Bullet casters know a mold rarely drops a perfectly round, on-size boolit every time; running each one through a diameter-matched sizing die corrects that so every bullet chambers consistently and shoots true. This die is built for .451-inch bullets specifically and drops straight into a standard lubricator-sizer press for fast, repeatable sizing at the bench.

Key Specifications

• .451-inch finished diameter matches this die to cast or swaged bullets that need to be brought to that exact size before loading.
• Hardened die interior holds its precision bore through repeated sizing passes instead of wearing oversize over time.
• Tapered mouth guides each bullet into alignment as it enters the die, producing a consistently cylindrical shape on the way out.
• 90-degree hole spacing is part of Lyman’s improved die design for smoother, more consistent sizing strokes.
• RCBS-interchangeable fit lets this Lyman die run in an RCBS lubricator-sizer press as well as a Lyman press, without brand-matched tooling.

Frequently Asked Questions

What diameter does this die size bullets to? It brings cast or swaged bullets to a finished .451-inch diameter, matching bullets that were cast slightly oversize or out-of-round.

Will this die work in a press other than Lyman’s own? Yes, it’s interchangeable with RCBS lubricator-sizer presses in addition to Lyman’s own, so you aren’t locked into one brand of equipment.
