I actually did this a year ago at a local range with my Rem 513-t (its a .22) to troll some newcomers. Some guy came up to me to try and correct me (he probably thought I was a newb with all my camo and shit), then hesitated when he realized I was hitting the 230 yd gong (makes a very quiet *pfft* when it hits that can't be heard if other shots are going on.
It's all about POA on target to get hits. I'm not ballsy enough to try it with my shotgun, although I am sure it is possible if you do a pull-pull style grip.
