I've had my H002 since June and have only used Winchester 555 plated so far, it fires fine and was accurate out of box. I've read that Henry stiffened the eject to prevent use of sub-sonic ammo and as a result it is a tad finicky over what fires/works. I was wondering how the pistol grip would handle on such a light rifle, and about AR-7 Industries parts quality / fit...thanks for the reply.
