Backed off for now and will reevaluate - probably come up with a harsher “solution” once the smoke and mirrors clears. I can visualize them manufacturing a handgun which will accept a round of each of the potentially tagged “armor piercing rounds” just so they can ban them because there is a handgun that accepts them.
Years ago I saw a single shot bolt action handgun at the local gun store that was chambered in 460 Weatherby. So yes, the #$&@!*&^ could make one to chamber every kind of ammo they wish to outlaw.
