Source hierarchy
Manufacturer manuals and official product documentation control setup, maintenance and compatibility. ATF and marketplaces control their own rules.
Retail descriptions and forum claims are leads to verify, not final authorities.
Safety boundary
Pages discuss equipment selection, bench planning, inspection, organization and official-source use. They do not publish charge weights, recipes, substitutions or pressure estimates.
When an article reaches load development, it directs readers to current published manuals.
Marketplace policy
eBay searches target presses, dies, scales, gauges, case-prep equipment, benches, manuals and parts.
Policy pages should be reviewed regularly because categories can change.
Used-equipment claims
A listing described as complete should be checked against its parts diagram and manual. Cosmetic condition should be separated from wear, rust, calibration and missing proprietary parts.
A cycle video is useful evidence but not a warranty.
Brand neutrality
Brands are compared by product class, model generation, support, compatibility and included parts.
Sponsored relationships must not suppress genuine limitations.
Corrections
Corrections should identify the page, model, generation, part number and strongest official source.
Generation-specific corrections are especially important.
