I recall reading an article a few years ago where they tested numerous big rifles and shotguns and measured the recoil. Cant recall if a 10ga was included, but the 3.5" turkey load in a 12ga won the prize for worst recoil. I know they had at least a .458 in the competition and I believe a .500 was in there. I shot 3.5 turkey loads from an 870 for years, and it certainly thumps and I can feel a tender spot on the cheek for a day after killing a bird. Shot a few birds from awkward angles where the gun was closer to bicep than shoulder and certainly felt those for a bit. Now I have a 3" gas auto and only shoot 3" shells, usually in the lighter higher velocity loads 10gagenut has mentioned. They still kick but not like the 3.5. I've been using a 20ga 870 more myself now that my son started turkey hunting. I choose to get birds close rather than try to extend my range, so any of above are perfectly adequate. My dad has an old single 10 that hasnt seen the turkey woods for years. May have to break it out for nostalgia someday.
