Hello, I recently got to try the new Winchester Supreme Elite slugs. 300grs. @2000fps.. My gun ,a Rem. 1100 with a 21in. factory rifled barrel and a Burris 4x short mag on top,don't like them. The best I could get out of them were 6in. groups. They also shot well below my point of aim. I then shot a couple of groups with my normal hunting slug,the Win. partition gold 385grs. @ 1900fps. inside 2in. at point of aim @ 80 yards.
