Right or wrong, the dude DOES sound like a sniveler. I don't like snivelers, but I'll still shoot his ammo. You're right about the gambling. One might assume increased demand for ammunition because of all the new gun owners, and that's probably true to an extent. But the uncertainty of the actions of the Biden administration add a degree of risk.
If we could only farm out ammo manufacturing to the Chinese, like we do with iPhones. It wasn't all that long ago when cases of Chinese ammo were stacked to the ceilings of gun stores, and we'd buy guns just to shoot the cheap ammo. Thank Clinton and everyone since then for today's ammo shortage. It could be solved with the stroke of a pen... if our leaders really wanted you to have ammunition.
