Fed, HW#7 is an awesome load for turkeys, this stuff is not your normal lead it's "Heavy weight" means it's 15gcc , it is equal to #4 lead . if your gun patterns then well then I would definitely use them. dont pass out tho when you go to buy them it's not cheap stuff but well worth the money.
Now what choke are you using in your SBE2 with those shells? I have a SBE2 also and would like to shoot those FED HW shells.
