Wilson Combat 300 HAMR 150gr BTSP 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
Speer built its HAM’R bullets specifically for the 300 HAM’R cartridge. This 150 grain version adds a boat tail base, which gives it a high ballistic coefficient of 0.417 for a 30 caliber bullet at these velocities. The soft point nose starts expansion on game, while the heavier weight helps it keep momentum and penetrate.

Intended Use
Wilson Combat built the 300 HAM’R to give the AR-15 real hunting power using a standard bolt and magazines. The 150 grain boat tail soft point is the heaviest hunting option in the line, and its efficient shape keeps it moving at over 1750 fps at 300 yards, which helps on longer shots at deer and hogs. It is a strong match for hunters who want more weight and reach from a light, handy AR.
Performance
With a ballistic coefficient of 0.417, this bullet leaves a 18 inch test barrel at about 2310 fps with 1778 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 300 HAM’R. 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.
