sorry mac not even close bud ...
My friend us old goose hunters were reloading this stuff long before they tried it in turkey rounds was just too too expensive for me at $25 plus a pound . Once I worked out some high speed steel duplex loads they were just as good. Dead is dead
(HEVI-SHOT)
50% W, 35% Ni, 15% Fe. Slightly irregular in size and shape, very dense – 10% heavier than lead, about as hard as or harder than steel. Corrosion resistant.
Can use slightly smaller sizes than you would with lead. Patterns extremely tightly - hard to do less than 70% with any choke. Any 12 ga. choke tighter than 0.665” will open the pattern. A standard Full choke, at about 0.691”, will pattern over 85%.

Hevi-Shot is a non-toxic alternative to steel with density similar to that of lead shot. This pellet produces impressive long-range patterns and down-range lethality.
Hevi-Shot is comprised of tungsten alloy (tungsten is an element which is harder than steel/iron), nickel, and iron. Hevi-Shot pellets are very hard and they must be contained within a special non-toxic shotcup.
When selecting Hevi-Shot pellet size, the general rule is to
use the same or one size smaller than you would have with lead shot or two to three sizes smaller than steel shot. With that said, this type of generalization cannot replace actual field testing on your part.
Our our collection of loads for Hevi-Shot are all in the Handloading Hevi-Shot manual.
Doesn't really matter your no. 7 hevi shot or No. 6 lead will kill just fine. Hope you land a nice big tom
Cheers
