Better listen to what TPhunter has told you I'll reiterate DO NOT shoot hevi-shot or for that matter any extrodinary hard alloy out of that stock barrel.I shot an ole JCHiggins for years and pitted the barrel using copperplated lead.Federal in there GameShock line of shotshell ammunition make some decent lead loads adequate for huntin turksin 2-3/4 inch hulls...It'll work you just need to know what you and your gun are capable of and apply it....good luck...One thing,you might check 82 I see your mentioning BB's,better make sure they are legal in your state your hunting in.I know here in Cali and other states its illegal to shoot shot larger than 2's..just a heads up...Oh the day of those ole high brass loads huh wingbone....killed alot of turkeys with em though...
