You gotta be kidding me! A .12 GA slug is devastating to any animal, especially a deer. I use a mode 870 shotgun with Haistings rifled barrel and scope. It likes the Lightfield slugs (Hybrid Elite) and is extremely accurate out to 100 yards. Have taken only two deer with my slug gun (both less than 50 yrds) and both of them dropped. Slugs properly placed are bad to the bone my friend. Good luck.
