Steer Manure.
He didnt have a “massive” arsenal. He had a FEW firearms. A couple of handguns, a rifle and a shot gun. Everyone of my friends is similarly equipped, several times over.
6,000 rounds is possibly adequate for a summar of training for a father and son. Given the fluctuation in ammo pricing thanks to O, one buys when the price is right. That reminds me: i am getting low on 5.56 NATO.
If one goes to the range once a week, and expends 100 rounds of ammo at each visit, then 6,000 rounds is a year's supply. There's lots of gun owners who have more.
