Wilson Combat X-TREME RNFP .458 SOCOM 300gr, 20-Round Box

Wilson Combat X-TREME RNFP rifle ammunition in .458 SOCOM (brand part no. A458300RNFP) pairs a 300-grain round nose flat point bullet with Wilson Combat’s custom-loaded brass cases. Wilson Combat builds the bullet by electrochemically plating copper over a precision-swaged lead core, then fully coating the base so no lead is exposed to the bore. The company loads every round with clean-burning, low-flash powder to protect night vision and cut down on fouling, and each batch is hand-inspected at its Berryville, Arkansas facility before it ships. For a big-bore SOCOM-pattern rifle built for defense or hunting, this load is meant to feed and perform consistently, not just look good on a spec sheet.

Key Specifications

• The chambering is .458 SOCOM, a big-bore round built around AR-pattern rifles for close-range knockdown power.

Frequently Asked Questions

Does the X-TREME RNFP bullet expand on impact? No, the round nose flat point design is a plated, non-expanding bullet built for reliable feeding and deep, straight-line penetration.

Why copper-plate the bullet instead of using a traditional jacket? Wilson Combat applies copper electrochemically over a swaged lead core and fully coats the base, which keeps lead out of the bore and reduces leading.

Where is this ammunition produced? Wilson Combat hand-inspects every batch at its Berryville, Arkansas facility using USA-made brass cases.
