Trying to get back into it, so I wanted to do something easy. I have found a lot of out of spec ammo that could cause you to have a bad day especially in a home defense situation. When you need your Evil Black Rifle to go bang instead of click. Make sure your ammo will fit into the chamber with a Sheridan Ammunition Gauge. Maybe some of the out of spec ammo will still fire and the gun may operate correctly, but I’m not willing to roll the dice on that one when my home and family are at risk.
