       Have you ever thought to yourself: “You know what would be cool? If I had a gun that fired Graboids from the movie Tremors (starring Kevin Bacon) rather than bullets.” Well we wondered that too and that’s why we’ve brought you our Maximum Expansion round.

       This Sub-Sonic hollow point is solid copper and doesn’t initiate expansion from force alone but rather from hydraulic pressure. That means once it’s passed through whatever it needs to and hits fluid tissue, it’s cavernous maw opens up and shreds whatever it hits. But wait, there’s more! Thanks to the diligence of our shop gremlins (and their love of ‘90s Kevin Bacon movies) they’ve managed to keep a 4.3 standard deviation on these monsters! If you’re looking for the best performing sub sonic round on the market, Kevin Bacon will tell you to look no further than the American made Maximum Expansion round.

Available in boxes of 20. No maximum limit.

All Grind Hard Ammo is guaranteed to provide excellent performance. If it doesn’t we’ll make it right.

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.
