I probably wasn’t clear in my statement. I meant that you can get a rifle in almost any pistol caliber. I thought they made that decision after the kid went into the WM in El Paso with an AR ‘pistol’. I have yet to see 556/223 at WM since but I’ve seen about every other rifle caliber.I really thought pistol ammo besides .22 was no more at Walmart. At least mine quit carrying it.
