I own many slug guns from the smoothbore Ithaca Deerslayer in 12 & 20ga, to a Mossberg 500 20ga (rifled/cantilever), to Remington 1187 in both 12 & 20ga (both rifled/cantilever), to the H&R Ultra Deluxe 20ga., to the Savage 220f. within the 150 yrd range the Mossberg 500, Remington 870 and the 1187 will be just fine, but if you want longer distance then the H&R or the Savage, my vote would be the Savage over the H&R. The Savage has a slight edge for accuracy near the 170 yrd range and beyond, the Savage is built and handles like a rifle, easier to carry cause of the lighter weight, the trigger is great, safety is as well. Top any of these shotguns with at least a decent glass or better like a Leupold VX-2, 3-9x40 and try the Remington Accutip 3" slugs (20ga) and you will be set. For the Savage the DNZ one piece mount/rings are best. For deer size game I will opt for the 20ga., they fly flat, no recoil, and knock the snot out of game......By no means am I knocking the 12ga,
