Yes, the Model 870, 1100 or 11-87 turkey shotgun can be used for deer hunting. You would need to change either the barrel or choke tube to one that would correspond with the ammunition you would be using.
The Turkey Extra Full and Turkey Super Full choke tubes are too tight of a constriction to use with deer loads. Listed below you will find our choke tube recommendations for deer hunting:
Rifled Slug Improved Cylinder Choke
Premier Accutip Slug Copper Solid Slug Rifled Choke Tube (or fully rifled barrel)
Buckshot Modified Choke
If you wish to order an additional choke or replacement barrel, you can do so through your local dealer, by calling our parts department at 1-800-243-9700, or directly through our online store at www.shopremingtoncountry.com.
