Remember these aren't grand pappies slug guns. They are 260gr ballistic tipped copper jacketed rounds traveling at close to 2,000ftps from a very accurate rifled barrel. I am confident that it would do the job with proper shot placement and a reasonable distance. My biggest issue would be hitting the shoulder/leg and not getting enough penetration.
