The longer the barrel the tighter the pattern, 28 is great but it will snag everthing you walk by. For me it a 24in barrel on my nwtf win. sx2 3 1/2 in mag with a .655 comp-n-choke and win extended range 3 1/2 6's well over 70 pellets in head and neck at 40yards.
18 1/2 inces on custom barrel and choke. outshot everything that came into gun shop here. everyone compares the new guns to my old rem. 870!
