I use as a hunting/skeet rifle the 870 28" barrel w. modified choke and it works very well with rem #8 birdshot.. I picked up the 590a1 for HD but also take it to the skeet range for sh**s and gigles and its very difficult as you would imagine to pick off the clays after 25yrds. Would using a different birdshot # help. do the larger size pellets spead less giving me better chances of hitting at 35 yards? I know cylinder bore is not he way to go for skeet but was just wondering anyway
