Just want to thank Clark @ allaboutshooting I was shooting my 96 Remington 11-87 NWTF 25th Anniversary edition with a 21" barrel and last year I was shooting #6 shot harvested a nice long beard with it I though this year I could not find any #6 shot in 3" mags so I wanted to try #5 shot LB's well he said my patterns were 2 blowing with my chokelooked looked like crap. Well I sent a PM to Clark at allaboutshooting he called me and said try this choke mine was to tight of a choke so I don't have the funds to buy a bunch of chokes. He says he has a short barrel Remington and this choke works with LB's #5 shot I say ok I'll take one. So anyways I got it yeasterday and stuck it on. So today got to the range at 20 and 35 yards my Remington 11-87 put big holes with a nice wide pattern around it took 2 shots at 50 now lost the big holes but tight even big pattern not a space on one of ether shots no bird would escape its patten.
