Well if we are talking about .22 rifles, my Ruger 10/22 has 30 round mags. And I have 15 of them, so I can put enough holes that sepsis won’t be a problem. My pistal has a 14 round mag and that many holes will make sepsis not an issue either.
We weren't but yeah, a few dozen .22LR rounds from a rifle barrel might do the trick. Those 10/22s are fun to shoot. Cheap to shoot, too.
