Preparation Tips: To ensure optimal performance, size the cases and run the expander ball of the sizing die through the case neck to achieve a perfectly round case mouth. Deburr and chamfer before loading.

Note on Appearance: A light stain may be present on the case neck due to the annealing process, which ensures proper case hardness. This residue can be easily removed by tumbling before loading. We recommend full-length sizing, trimming, and chamfering for the best results.

Safety Warning: This product contains lead, a chemical known to the State of California to cause cancer, birth defects, or other reproductive harm. For more information, visit P65Warnings.ca.gov.
