Full capacity magazines for handguns and rifles are going fast also. Some sales are made by plain folks hedging their supply, and some sales are speculators stocking up for when a 30 round ar mag will be going for 50 or 100 dollars.
Gear up, ammo up, mag up
It’s the American way!
Don’t forget, a muzzle loader is a great way to deliver 300 grains.
In a cannon maybe. 70 to 100 max for a .50 cal muzzle loading rifle.
A lot of people underestimate the amount of brutal short range kinetic power a muzzle loader has. Hard lead balls or home poured buffalo bullets have no problem knocking holes through engine blocks.
