i picked up a 20 gauge h&r ultra slug gun with a leupold scope at harry's last year and i plan on useing for deer season this year, i sighted it in at centrel jersey rifel & pistol range in jackson a few weeks back, this gun is on the money out to 180 yards useing 3 in fedrel sabots, i was all ways a 12 gauge guy, but trying to sight in a 12 gauge slug gun is bruttel, i was wondering if anybody ever had any kills using a 20 gauge slug gun.
