For turkeys, sizes 5 to 7 will get the job done nicely and are popular choices. Winchester uses its proven Shot-Lok technology in its Xtended Range Bismuth loads.Ī number of manufacturers offer three-inch, bismuth-based, 12-gauge shells with No. Bismuth-based shells cost more than steel, but in terms of ballistic and terminal performance they are far superior and well worth the extra few dollars. This was a problem early on, but today’s bismuth loads are alloyed with 4 to 6 percent tin to provide the necessary cohesiveness to hold together as it departs the barrel and impacts the target. BISMUTHīismuth by itself is frangible that is, it breaks apart upon impact. Hevi-Metal Turkey, which combines steel and Hevi-Shot, is one such example.
#Bismuth shot 5 plus
No manufacturer sells a turkey-specific, steel-only load, though some, like Hevi-Shot, offer loads with steel plus another material.

Hevi-Metal Turkey features a combination of steel and Hevi-Shot. Unlike lead pellets, steel shot retains its true form from the minute it exits the barrel to impact, and close-range penetration means deeper, more lethal wound channels. Perhaps equally important is steel shot doesn’t flatten out upon impact. Steel shot also spreads less and delivers tighter shot patterns than lead, meaning more pellets strike the target. 4 steel load may contain as many as 300 pellets depending on the charge, while a lead shell of the same size contains just over 200. Steel shells contain more pellets than their lead counterparts of the same size. Our online platform, Wiley Online Library () is one of the world’s most extensive multidisciplinary collections of online resources, covering life, health, social and physical sciences, and humanities.But steel shot has some advantages over lead and can certainly be deadly on turkeys.

We conclude that TBT shot presents virtually no potential for acute intoxication in mallards under the conditions of our study. Bismuth concentrations in kidney and liver (<16 ppm) were near detectable limits and did not differ (P = 0.34 and P = 0.22, respectively) between dosed and undosed ducks.

Tin and tungsten were not detectable (<6 ppm) in kidney or liver samples. No gross lesions were observed during postmortem examinations, nor did histopathological examinations reveal any evidence of toxicity or tissue damage. Differences in blood calcium (P = 0.02, β = 0.12) were judged to be unrelated to shot exposure. Except for blood calcium, none of 24 hematology or blood chemistry variables measured 3, 11, 21, and 32 days post-dosing differed (P ≥ 0.09, β = 0.16) between dosed and undosed birds. Behavior of dosed and undosed ducks (both n = 20) was normal throughout the trial, and no differences were detected in food consumption (P = 0.52, β = 0.39) or body mass change (P = 0.71, β = 0.15) relative to treatment. Eroded shot evident in radiographs taken 11 days post-dosing indicated acute exposure to the constituent metals, but no dosed or undosed birds died during the trial. Ducks were monitored for 32 days for evidence of intoxication. We evaluated the acute toxicity of an alternative shot by orally dosing 20 8-week-old game farm mallards (Anas platyrhynchos) with 12-17 pellets (x̄ = 1.03 g) composed of tungsten, bismuth, and tin (TBT). Steel shot is required for waterfowl hunting in the United States, but hunter dissatisfaction with steel's perceived ballistic performance has reduced compliance with steel shot laws, contributed to the loss of waterfowl hunters nationwide, and renewed interest in an alternative non-toxic shot with ballistic qualities similar to lead shot.
