I found that the 4's that I used worked good for the decoying mallards and woodies.
I never used it for pass shooting .
Hevi-Steel has a density of 9.064, against the density of steel coming in at 7.86. This brings the new Hevi-Steel in close to density figure of 9.82 Of bismuth and Hevi shot has a density of 12.
I would like to buy Hevi steel to reload . I am going to check into it for next year.
From what I have read on Hevi shots web site and other places . Remington bought the rights to load and market Hevi shot , but Hevi shot retained the rights to keep selling loaded ammo under their name also.
This ammo is loaded by Remington or Poly Wad .
Poly Wad was the orignal company to load Hevi Shot for Hevi Shot .( I got to shoot so of the pre aproval loads several years back)
Poly Wad loads the Hevi Shot Dead Coyote load and the OO buck load amoung others
If you go to Hevi Shot's web site and look
here and down load the Hevi Steel down load it explains it a lot better
