125 yds with a 45cal. I guess it will do it but you could watch the slug fly through the air. They leave the barrel at around 1000fps. By time they get to 125 yds what are they traveling? 68 fps. Most snipers could probably duck out of the way when they saw the flash of the muzzle. If your talking 357, 327, 41 or probably any other rnd beside a 45 then it would be realistic
Concentrated power is not rendered harmless by the good intentions of those who create it.
