And I fully understand this. Lead 4's, Steel 2's. Technically same difference. But fire both at 1400fps with a 10mph crosswind and see who drifts more at 40 yds. See what has more sustained energy at that distance.
I grew up shooting in the great lead days and have since made the switch, to much dismay. I now shoot almost exclusively Hevi-Metal and now ITX reload's in both 12ga and 20ga.
