I recently bought two boxes of Aguila Hyper Velicity .22 lr ammo. I fired off a couple shots through my Ruger Mk II Standard model handgun without any problems whatsoever. But! My concern is... is this ammo too HOT for semi autos? I mean I would compare the ammo to .22 mag. Every shot fired I saw a flame or Muzzle flash about a foot long. While shooting milk jugs and cans the targets were destroyed. I was like This is Unreal for a .22lr! Is it safe to keep shooting this ammo? or will it harm my semi auto?
