Hey guys, first time on this site. I can already tell this site may get me fired at work . I have some questions about aftermarket choke tubes if anyone can help me out. I have had a shoulder injury for a long time, and I'm limited as to the amount of recoil I can take in the shoulder area; so I have been shooting 2 3/4" mags for a long time out of my Remington 870 with factory x-full choke. I'm interested in purchasing a new choke, possibly one with vents/ports that supposedly reduce "felt" recoil, hoping I can move up to 3" mags to extend my effective shotgunning range on longbeards without damaging my shoulder any further. I've heard and read a lot about Kick's choke tubes, and have seen tons of other brands in catalogs and such. Do these tubes really make a difference in recoil? Has anyone out there tried a Kick's in their in 870 with 5 or 6 shot? Thanks guys....
