       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.

Amazing, very happy.

Robert ODell
Best home defense ammo

I was a home based FFL for many years. My defense firearm is a Suppressed Sig Ratttler 300BO. I tested this ammo using 6 gallon jugs of water. Shooting from 15 yards the bullet passed through 4 gallon jugs, damaging the 5th but remaining in the 4th. The expansion was just like the picture advertised. I would highly recommend this ammo.

Fast and Reliable!

Great quality ammo. Everything came quick and with no issues, highly recommend

Martin Bosworth

These are very accurate and are devastating with proper placement. They are much preferred over your new fragmenting rounds. We process what we kill and don’t like finding fragments in meat!

Thanks and keep up your QC… I recommend you guys constantly!

Happy New Year!!

Best ammo ever

Just the best! No questions whats so ever
