I just bought a H&R ultra slug gun 24inch heavy rifled barrel in 12ga from a guy I work with. $300, bucks never fired with a nikon prostaff 3x9 on top. I took to the range and tried 5 different types of Saboted ammo. Best of show went to the Hornady american whitetail 2 3/4 325gr. load, three shot at 100yards under 1 inch.first two shots in the same hole, the third just above the first two. Awesome! It will be a 200yard death stick on deer.
