Wilson Combat A300HMR135HB Centerfire Rifle - 300 HAM'R, 135 gr Speer HAM'R Bonded, 2450 fps, 20 Rounds/Box, 10 Boxes/Case

Wilson Combat's 300 HAM'R ammunition loaded with Speer's 135-grain HAM'R bonded bullet delivers the kind of terminal performance serious hunters and tactical shooters demand. Built on the premise that you don't always need maximum penetration—sometimes controlled expansion and quick, reliable kills matter more—this load pairs a proven bonded projectile with a velocity sweet spot (2450 fps) that optimizes energy transfer without over-penetration. If your rifle is a modern sporting carbine or compact hunting gun in 300 HAM'R, this is purpose-built ammunition that performs in real firearms, not just test barrels.

Wilson Combat manufactures and hand-inspects every round at their Berryville, Arkansas facility, which means you're getting ammunition engineered to exacting standards. The Speer HAM'R bullet is exclusive to Wilson Combat and combines a bonded-core design for weight retention with a profile that reliably expands to over 5/8 inch. Whether you're zeroing in on medium to larger game in the field or training for defensive applications, the ballistic consistency and accuracy of this load give you confidence in your shot placement.

The brass is USA-made and tumble-polished post-manufacture for reliable feeding and extraction. Wilson Combat uses clean-burning, low-flash powders that preserve your night vision on low-light hunts and reduce fouling in your action. Each box contains 20 rounds, and the ammunition comes in cases of 10 boxes—convenient for stocking your reloading bench or keeping a ready supply at the range.
