Even a felon can own a black powder firearm. Not considered a weapon.
I was in Wally last night to buy some feared handgun ammo to feed my short barrelled black handgun AR. They still have plenty and should until they deplete all their warehouses.
I made conversation with the gun clerk, asked him about the Henry Rifles he had behind him on display. What Caliber?? UH, 44, 357, and 45 colt, all handgun cartridges in a rifle designed to hunt with. HMM, gonna have guns with no bullets to sell? Did not think that out very well. Several 223 bolt action rifles on the shelves.
If you follow the logic, they will soon stop selling Cellphones. Stupid people misuse them every day and kill people. Prescription Opioids will be off the table in the pharmacy, people sell those and deaths occur. Sodas and other sugary foods will be off the shelves, people are killing themselves with obesity and Wally is full of the waddlers and scooters full of them also. When they quit selling all of that stuff, we will all be safer.
