The L.E. Wilson 50 BMG Case Gage (brand part no. CG-50BMG) is an L.E. Wilson reloading accessory. It’s machined to 50 BMG SAAMI reference dimensions, so dropping a sized or trimmed case into the gage shows at a glance whether case length and headspace are in spec. Handloaders use a tool like this for a fast, repeatable in-spec check on brass after sizing or trimming, without setting up a comparator.

Key Specifications

• Machined specifically for 50 BMG brass.
• Checks case length and headspace against SAAMI reference dimensions after sizing or trimming.
• Gives a quick go/no-go visual reference without a separate comparator or micrometer setup.
