Felow GTers, I have several handguns but I am evaluating the purchase of a shotgun for home defense & SHTF scenarios. I have never owned or had much experience with shotguns and would like some help. I have been looking at the Rem 870 Tactical. My budget is limited, so I need to stay below $500. I would like to be able to shoot buckshot and slugs depending on the occasion. I have been reading about sabots and rifled barrels... I am assuming the 870 does not have a rifled barrel. The question is, I can shoot buckshot and slugs but NOT sabots? I am guessing a rifled barrel would be more accurate at long range. However, for Home Defense / target shooting applications, I may not need long range accuracy. For those of you who have the 870, what is the longest distance you can effectively hit a target with a slug? buckshot? Comments, suggestions are welcome... Thanks!
