What is considered a good barrel length for turkey? Mossberg makes a mossy oak camo Model 500 with a 20" barrel model with a collapsible stock and pistol grip like on an AR. It comes with a turkey choke. I believe they call it the Tactical Turkey model. It looks like that gun could easily also be used for home defense as well, if you just pulled the turkey choke and put a cylinder or improved cylinder choke in its place. Does anyone know if that model comes with any chokes besides the turkey choke? Also, is 20" enough barrel for turkey?
