The Wilson Combat 458 SOCOM Cartridge Gauge (brand part no. TR-458SOCOMCG) checks loaded or fired 458 SOCOM cartridges against SAAMI-spec dimensions before they ever reach the chamber. Dropping a round into the gauge quickly reveals an oversized case, a bulge, or an out-of-spec case length, letting a handloader catch a bad round on the bench instead of in the field.

Key Specifications

• Sized to 458 SOCOM SAAMI-spec dimensions for an accurate reference check.
• Checks case length, headspace, and body dimensions in a single drop-in test.
• Machined from hardened steel for a gauge that holds its dimensions over years of use.

Frequently Asked Questions

Does this gauge check both loaded and fired rounds? Yes, it can be used to check loaded ammunition before shooting or fired cases before reloading them.

What does it mean if a round doesn’t drop fully into the gauge? A round that doesn’t seat fully flush is oversized in some dimension and should not be chambered until the cause is identified and corrected.
