I've been working at the school as a teacher for many years now, and it's important to me that the kids graduate with some sort of military knowledge base. To do this, I show them weapons and ammunition live. A month ago, I ordered 10mm revolver ammunition so the kids would understand the drill. Next week I'm going to show them the Remington 700 rifle; I've already ordered the missing ammo, such as rings, from https://ballachy.com/best-scope-rings-for-remington-700/. Specifically, Vortex Optics Pro series scope rings.
