This is Buffalo Bore's take on a serious .40 load—the Heavy Strictly Business +P features a 180-grain jacketed hollow point optimized for stopping power in real-world defensive scenarios. The muzzle velocity clocks in at 1100 fps with 484 ft-lbs of energy, giving you ballistics that perform exactly as advertised out of actual carry guns, not inflated lab numbers.
The key to this load is the flash-suppressed powder. Most defensive situations happen in low light, and the last thing you want is to blind yourself after the first shot. Buffalo Bore engineered this round to minimize muzzle flash while delivering high velocity at lower pressures. The 180-grain weight gives you solid penetration with the controlled expansion you need from a hollow point. This round is field-tested in real firearms across different barrels and platforms, which matters more than theoretical performance numbers.
You're getting brass cases that won't jam up your range time or reloading setup. The 180-grain bullet weight is where many defensive experts land for the .40—it strikes a balance between velocity and impact that's been proven across actual use and testing. At 1100 fps, this load sits in a performance sweet spot that's manageable to shoot while delivering the energy needed when it counts.
Because this is a +P load, it requires a firearm rated for +P ammunition. Not all .40 S&W platforms handle +P rounds safely, so before you pick up a box, check your gun's manual or contact the manufacturer to confirm your pistol is +P rated. This step takes two minutes and keeps everything running properly.
This ammunition is rated for +P, which means it generates higher pressure than standard .40 loads. You need to confirm your firearm is specifically rated for +P ammunition before using it. Check your gun's manual or contact the manufacturer—most modern defensive pistols handle +P, but some platforms don't. Never use +P ammunition in guns that aren't rated for it.
Most defensive encounters happen in low light or darkness. Regular powder can create a bright muzzle flash that temporarily blinds you after you fire—not ideal when you need to see what's happening next. Buffalo Bore uses flash-suppressed powder to minimize that flash while maintaining velocity and energy, giving you a tactical advantage if you ever need to use your gun for defense.
The 180-grain bullet is heavier than common 165-grain loads but lighter than some specialty rounds. This weight gives you deeper, more controlled penetration while the hollow point expands reliably. Many defensive professionals prefer 180-grain for the .40 because it delivers solid ballistic performance without excess recoil, making follow-up shots manageable.
Yes, Buffalo Bore uses brass cases, so you can reload them after firing if you have the equipment and knowledge. The casings are durable and suited for reloading operations.
