Wilson Combat 458 SOCOM 300gr RNFP Overview
Wilson Combat is best known for hand-fitted 1911 pistols and premium AR-15 rifles built in Berryville, Arkansas, and the company loads its own ammunition to the same standard. Every Wilson Combat load is assembled with new, high quality brass, carefully selected primers and powders, and bullets from makers such as Hornady, Sierra and Speer. Loads are tested in real firearms for function, velocity and accuracy, so what you buy is ammunition the company trusts in its own guns.
Bullet Design
The 300 grain X-TREME round nose flat point is a plated bullet with a broad flat nose. A flat point does not rely on expansion; it crushes a wide channel and tends to penetrate in a straight line, which makes it very consistent. The plated construction also keeps costs down, so this load works well for practice as well as field use.

Intended Use
The 458 SOCOM turns an AR-15 into a big bore rifle, and this load uses that power well. Nearly 2000 ft-lbs of muzzle energy and a heavy, flat-nosed bullet make it effective on feral hogs and black bear at short to moderate range, and the moderate velocity keeps recoil manageable. It is also a dependable choice for range time and for getting familiar with the cartridge.
Performance
With a ballistic coefficient of 0.177, this bullet leaves a 16 inch test barrel at about 1700 fps with 1926 ft-lbs of energy. Actual velocity varies with barrel length, temperature and the individual firearm, so confirm your zero with the exact load you plan to use. Shooting a few groups at your usual distance is the best way to see how it performs in your own rifle.

Firearm Compatibility
Use this ammunition only in firearms chambered for 458 SOCOM. Check the marking on your barrel before loading, and consult the maker of your firearm if you are unsure whether a load is suitable.
Quality You Can Count On
Wilson Combat loads every round with new brass rather than reloaded cases, and checks the ammunition in real firearms. Consistent cases, primers and powder charges are what give reliable feeding, clean ignition and accuracy from box to box.
Choosing the Right Load
Match the bullet to the job. Expanding hunting bullets are built for game, match bullets for paper, and heavy flat points for deep, straight penetration. Think about your typical distance, the size of the target and what lies beyond it, then pick a load and practice with it so you know where it hits.
Storage and Care
Store ammunition in a cool, dry place in its original boxes, away from solvents and lubricants that can contaminate primers. Inspect each round before loading, and set aside any with dented cases, loose bullets or corrosion.
