Anyone here tried to duplicate the 20 ga. WinLite loading? I'm reloading for my 13 year old son and really like the WinLite shells. I cut one open and found 7/8 oz of shot, a WAA20 wad and about 9.8 grains of powder for a velocity of 980 fps. I assume the powder is Winchester Handicap, but don't know for sure. Any help?
