Tungsten Super Shot is the densest shot material on the market at 18g/cc.
MM, I see Hevi shot is introducing a new waterfowl load "hevi xii" 12g/cc 25rd box,not on shelves in my area yet,but hevi x is composit tungsen like bismouth but more dense and heavier than bismuth but hevi x doesn't have the density or weight of hevi 12g/cc think it's 10.1? regardless still better than all steel loads for longer range shots
fyi
Yeah it’s confusing that hevi shot is not more upfront with their densities.
Hevi metal is steel and bismuth blend ~$30 per box ( old boxes were real hevi shot)
Hevi X tungsten is only 10.1 g/cc ~$40 per box
Hevi 12 is 12g/cc ~$50 per box
