My buddy took the cheaper route. 870 super mag, undertaker choke in clearance bin at basspro $7. Rem Nitro 3.5in #4. I didn't see the target but he said poa/poi was spot on at 30yds. We worked a bird opening day of that season shot came 28yds he shot bird folded like a Mack Truck hit it. We get to cleaning the bird a bit later. Both legs broke, pellet holes through them 9 hits through the breast. Then 6 hits in head an neck. Remington Nitro Turkey is a good shell. That year he killed both birds he shot at. But it looked like after 30 the drop off in performance was substantial.
