The original green Remington Hevi-Shot shell was made in two 3" weights, a 15/8 oz. @ 1225 fps and a 11/2 oz, @ 1300 fps. and In 31/2", 17/8 oz. @ 1300 fps and 13/4 oz. @ 1225 fps. I killed a bunch of turkeys w/ the 3",15/8 oz. load w/ 5's and w/ 6's and the 31/2", 13/4 oz. In every gun I patterned both the 3' and 31/2" heavier loadings @ 1225 fps patterned better than the 1300 fps shells. I've still got over two cases of the turkey loads and wouldn't hesitate to hunt turkeys w/ them again, but since the advent of the Hevi-13, 7's, they are being used on ducks and geese. At $18/ box of 10, that's a great price for hunting turkeys or ducks.
