The MFS ammo we sell in store is fine to use at our ranges. MFS has a mild steel jacket, and after extensive testing it was approved to be range safe for TSE.
We inspect all ammo before you hit the bay with it, and the above ammo types that Justin has listed are non-conducive to our range.
If you have questions or concerns about ammo you want to bring in, please ask one of our range officers or call us first.
We have MANY range safe options in our facility you can purchase as well!
