Hey it's my birthday too!!!
Can you let me know what vertical grip that is? Thanks.
Mine doesn't shoot remington bulk ammo very well from walmart. CCI sub-sonic works well though.
I wold think that there would be a general consensus on which ammo works decent.
I will shoot 250 of each and see what happens I guess
Nice setup hope to see it at FNS next week, along with you and your son.
