Maxiumum expansion


Maximum Expansion® Technology is used to produce projectiles that create the largest wound channels of any bullet you can buy. These cavernous hollow points are designed to expand upon contact with a fluid-based medium through hydraulic energy. They do not expand on dry mediums like wood, drywall, bone, or sheet metal. The expansion process of Maximum Expansion technology is very different than that of a traditional lead jacketed bullet that expands when it comes in contact with a hard surface – we designed these bullets to expand where the expansion is needed and that is in the vital zone of your intended target.

  • Unequaled expansion providing outstanding terminal performance
  • Largest expanding bullet in the industry while offering excellent penetration
  • Exceptional accuracy due to state-of-art manufacturing process
  • Machined solid copper bullets not swaged/formed
  • Razor sharp petals for maximum terminal performance

Made to run in a suppressed gun only with silencer Or bolt gun. 

May not cycle properly with out silencer.

Great Expansion

Shoots straight and true while suppressed. Knocked down hogs without issue. Bullets all expanded upon impact as described. Lethal rounds!

Best subsonic on the market

Tried finding the right subsonic ammo to run through my AR pistol after trying several different brands with inconsistent results I tried grind hard‘s subsonic ammo and haven’t had a single failure. Excellent product highly recommend!

Simply the best

Been hunting hogs with this stuff for about a year now (Really need it to come back in stock) and I've got to say. This is the most lethal sub defense round I've used. Upon impact it sounds like a catcher catching a fast ball in his glove. ''THUMP" and down goes the hog.
