“Train, keep training, carry your gun whenever you legally can.” – John Benner

We have a limited supply of ammunition that we can sell for our classes. We have 9mm, .223/5.56 and 7.62×39. We ask that you make every effort to supply your own ammunition for your class. Please bring what you have to class and we can supplement the ammo you bring up to the minimum round count. We will need to replace our ammo at current market pricing, therefore; we will be charging students current market prices for our supply. Our supply of ammunition will be sold to students during our classes on day 1. We will not sell ammunition for students to take home.

If you will need ammunition, please let us know 3 weeks in advance of your class.

Additionally, we have lowered the required ammunition count for our classes and will work with our students on keeping the round count low to meet your needs, including dry firing for some drills if you so desire. As a reminder, if you are borrowing a TDI gun, we do not allow reloads or remanufactured ammunition. We will accept remanufactured ammunition from Midwest Ammunition or Black Hills Ammunition. If you have any questions or concerns, please email us at tdiohio@gmail.com.
