I have a friend who is a quadriplegic and has no use of his limbs. He wants to shoot competitively. I shoot PRS and haven't ever shot f class but it seemed like it would suit his situation perfectly. We went out yesterday to see what he could do and with 55gr fmj bulk ammo in an AR he was stacking them into a pretty nice group on a 415 yard steel plate and he hadn't ever shot that far. So I'm going to tune a load for his AR and handload for him. Im thinking a 73 or 75gr eldm with xbr8208 in lake city brass would do well but if there's a better option that will fit and feed from an AR mag im open to it.
