Cg7,most manufactured turkey loads nowadays are made with alloys that will harm a standard barrel,particularly ones with tight constrictions!You can purchase chokes made for steel shot but it depends on just how much you plan on shooting it.I shoot steel loads out of my modified barrel thats stock on my 870 and haven't had a lick of trouble in the duck blind!Even with all the shot variations available nowadays to todays modern turkey hunters I still shoot lead out of my 10gauge and have for about 25 years!Doesn't mean its the best or that there isn't anything else out there thats better,obviously heavi-shot has taken the turkey world by storm.But with that said my own lead loads were consistently killing gobblers before heavi-shot ever came into existence and will continue to do so as long as I'm able to put my sites on any longbeard I'm after!So the answer simply put is yes lead will kill turkeys!!
