Lead-Free Turkey Loads: Which is Right for You?
A number of manufacturers offer three-inch, bismuth-based, 12-gauge shells with No. 3 to No.7 shot. For turkeys, sizes 5 to 7 will get the job done nicely and are popular choices. Bismuth is also available in 2 3/4-inch 20-gauge shells, typically loaded with No. 5 and No. 6 shot, for those who prefer small-bore guns.
