Lee Precision's 0.429" diameter bullet sizing kit is designed for easy and fast sizing of cast bullets and fits any single stage reloading press with standard 7-8x14" threads.
The sizing kit includes a special container for sized bullets, automatically seats and crimps gas checks, and eliminates the need for a top punch.
When using the kit, bullets should be lubricated first, and the sizing die chosen should be .001" larger than the bullet's groove diameter for optimal results.
