       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.

Excellent expansion!

I've taken several hogs and deer with this round using bolt action and AR-15 rifles. Great expansion and accuracy! It's my go-to 300 Blackout round.

Josh Barber
So far so good! Shipping was extremely quick!

The max expansion, in my opinion, is one of the best hunting and self defense rounds made. Lethal up to 100 yards on whitetail so far. Most of the time I don’t get a pass through shot. Super quiet with a can.

Recently un-jailed my can and did some work with my intended home defense ammo. It fed flawlessly through 250 round and had consistent grouping. I will buy more.

Amazing, very happy.

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.
