From people I hunt with they say it would at close range. Haven't seen it in first hand though.
Also you have to go to specialty stores or order them, academy doesnt have them. Referring to BB lead shot.
I would NOT shoot a hawg with bird shot...not even # 4
If it's a tame hawg you might get by with pissn him off, if it's a rooter he might just feed you that shotgun
