 Cases will NOT say Grindhard on them due to supply chain constraints.

We are struggling to keep prices down on primers, projectiles and cases and do see copper and lead prices to continue to increase.

God speed everyone in these crazy times

Reliable and consistent

I've been using Grind Hard Ammo for about a year now and after shooting about 500 rounds, I have had no failures or malfunctions. The ammo is consistent, accurate and never a concern while training. I would highly recommend to anyone on the fence. I will continue to use Grind Hard Ammo and support a small business owner.

This company top to bottom is great! The turn around time from order to product in hand was incredible. Not many companies can you DM the owner and have a conversation, and during that conversation he gave all the credit to his employees. Will never order from another ammo manufacturer.
