Lee Precision .285'' Diameter Classic Bullet Size Kit

The Lee Precision .285'' Diameter Classic Bullet Size Kit is a straightforward solution for handloaders who cast their own bullets and need a reliable way to size them to precise specifications. This kit is designed for single-stage press use and handles one bullet diameter—in this case, .285''—making it an economical choice if you're working with a single caliber or plan to build out your sizing equipment incrementally. If you're new to bullet casting or stepping up from undersized cast rounds, this kit delivers the core functionality you need without unnecessary complexity.

The kit works by pushing bullets through the sizing die nose-first, which eliminates the need for special nose punches. Gas checks are automatically seated and crimped as the bullet passes through, so you don't need to manage those separately. Sized bullets drop into a capture container, keeping your workspace organized and your finished rounds ready for the next stage of reloading. The die threads to standard 7-8x14'' single-stage press threads, meaning compatibility with most common reloading presses on the market.

A practical note for setup: the push-through punch replaces your standard shell holder in the ram, and you won't need a separate top punch for this operation. Many reloaders find this straightforward design appealing—fewer moving parts and setup steps mean less fiddling and more time actually loading ammunition. Because this kit sizes bullets to a single diameter, you'll want to verify that .285'' matches your intended groove diameter (Lee recommends selecting a sizing kit that's .001'' larger than your bullet's groove diameter for optimal fit). As with all Lee sizing equipment, you'll supply your own press and bullet lubricant—typically liquid alox works well for the sizing process.
