Got two Ultra slug guns here. I shoot the 12 gauge Deluxe using 2-3/4" Brenneke Heavy Field Magnums & 3" Gold Magnums and accuracy is fantastic. My oldest son, Hoss1, shoots a 20 gauge and it is probobly a touch more accurate. He is shooting Remington 3" CopperSolids. Both have Simmons straight 4X scopes. I've taken plenty of deer with mine, most drop on the spot.
