My question is... Why would you have to buy another barrel? The factory barrel is quality enuff for anything you would do in the turkey woods or any where else for that matter.
Those 870's with the 26" barrel and the right choke/shell combo are killer's!
My buddy has one with the JellyHead .660 and shoot's an awesome pattern. I think I would have bought a choke tube and a few boxes of shell's and tried the 26" barrel, that 2" of barrel on the carlson's isn't gonna change the game that much.
Just sayin.
