Federal 00 Tactical has been the most accurate buckshot in all of my guns, with TAP 00 red hull being second or even. Shotguns are picky beasts and while one 870 may shoot Federal extremely well, your identical 870 may not. Buy a few boxes of both and pattern test them, buy the one that patterns the best out of your gun. Low Recoil loads are the best choice for HD use. Shotguns don't rely on velocity for wounding like a 5.56 round and a reduction in muzzle velocity doesn't make much difference in terminal performance. It also reduces the chance of over penetration as the shot isn't moving quite a fast. These rounds also allow for more accurate shooting and faster follow up shots. The difference in terminal ballistics between a standard and reduced recoil shell will be negligible. Hopefully, you are shooting a pump not an automatic. Some automatics don't cycle reduced recoil shells, so a lot of testing must be done. Federal Tactical is the gold standard for buckshot accuracy, but I have found TAP to be just as good. Remember, every gun patterns differently and pattern testing is the only way to tell.
