No real reason,used my 870 the last 16 springs,just looking for a project to tweek on.Really looked at the single shot Hand R'S and Rossi,but the idea of being able to make a follow up shot or use the right choke,shell,for a particular shot has appeal to me.Maybe straight 7's with a open choke for heavy cover hunting,5's or 6's with a tighter choke in fields or pastures,all in the same gun.
