Mine doesnt hurt either. The followup bruises are smaller than the first. In order to induce bruising of that magnitude, I agree with CE, you have to snip a large capillary at least, but to do it repeatedly, thats kinda strange. I'll keep shooting it. First because Im probably retarded and dont know it yet, but also because I have to see if I shoot in a diff place on the delt will it happen again.
