It' s just pain. Im not trying to put you down or anything, but i have always thought that it hurts but who cares. Maybe its because i have a bigger brother who has given me way to many charly horses and im used to it. I have never really been flinchy because i just take the hit. I do however get pissed when the scope hits my eye, i just make sure that i move back a little then don' t worry about it.
