Buying Guide: Key Purchase Considerations
- Batch size and tumbler capacity: Larger bags save per-pound cost but require bigger tumblers and more storage.
- Treated vs. untreated: Treated media includes polishing compounds for a shinier finish; untreated media relies on separate polishing steps if desired.
- Brass condition: For heavily tarnished or dirty brass, choose a batch and material known for robust cleaning and gentle abrasion to avoid bending or denting casings.
- Reusability: Some media is reusable across multiple cycles; this affects long-term cost and waste considerations.
- Environmental and safety concerns: Corn cob media is generally eco-friendly, but verify any additives or coatings with product specs.
- Bulk vs. hobbyist needs: Bulk options suit frequent reloaders, while smaller packs fit casual use or testing new media types.
