My Benelli M1S90 is zero'd for 25yds for defense.  Anything further I just know to aim higher.  If its needed closer than 25yds, I aim center mass and it still takes down whatever is near center mass.

Works for me.

I dont "zero" bead sighted shotguns. I try a variety of slugs and then stock up on whichever brand and type prints closest to point of aim at 25M.

Why do you zero at 50 yards/meters?  If zeroed there, what's the drop at 100 yards?

BTW, mine is zeroed at 100 yards.

In a defensive shotgun how often to you think in most settings you will be  justified in shooting 100yards?

i have of recent switched to a 25 yard zero on all my fighting shotguns why little if any differance in my POA/POI with the slugs of my choice. in my 18 inch smooth bore guns at 50 yards/

Bead sighted HD guns get zeroed at 25M.

Hunting guns get zeroed at 50M.

100yds with a slug gun is no longer self defense.

A Benelli I used to own, appeared out of the box to be zeroed POI/POA for 100 yards.

Shooting at 25 and 50 was dead on, for the hell  of it I fired at 100 from the prone since I hadn't shot slugs much before.

I aimed for the head of a silhouette expecting the slugs to drop into the chest.

Five rounds=five head shots, much to my surprise. Five more aimed for the chest=five solid chest hits. And that was on a brand new target, spotting each shot with a scope.

While 100 yard shots aren't exactly "defense" anymore for most, shotguns with slugs can hit a lot further away than most people think.

I do not feel a smooth  bore shotgun is accurate typically at 100 yards.   I like to sight in at 50 and would not use a shotgun for anything much farther than that unless I had to.

25m any thing more then that i use a ar.  with a somebore your not going to get to much distance outa it. mine is a 18.5 inch smooth and i do 25m tops with slugs.  and i would only use them in thick brush if i had to and shot gun is a good go to gun but not right for all things

Some Rack grade 870s can be a foot off right or left at 100 yards when zeroed at 25 yards. You should only shoot at the distance you can guarantee hits. Everyone should know ,regardless of the zero on the gun, where it will hit the target at 25-50-75-100 yards. If you can make a head shot at 100yds great but if you can't don't attempt it, get a rifle. The best range for slugs is 20-60 yards for defensive purposes thus a 50 yard zero. Bird shot is good to about 10-12 yards and 00buck to about 25yds; of course this all depends on the shotgun/ ammo combination as it will vary. One of the most important things you can do with your defensive shotgun is to make a pattern card. To do this you start a 5 yards and shoot an IDPA target with 1 round of bird shot then back up and shoot another until you get pellets off the target. That distance is where the use of bird shot should stop. Do it again with 00buck but start at 7 yards. When the 00buck pattern is wider than the target you need to switch to slugs. with slugs start at 20 yards and back up until you miss the -0 and -1 zone. that is the limit of the gun ammo you have. Now make sure you record that info and keep it with the gun then you will know exactly what ammo does when shot out of that particular gun. I have seen this on a index card taped to the stock on some "Department" shotguns.

The NRA PPC shotgun match requires 5 rounds at 50 yards on a B-27 target. Most shotguns can hit the ten ring all day long at 50.

It isn't out of the question for a SWAT team to find themselves in a building such as a Walmart or Lowes that may have 200 yard lanes of fire.  While that's way beyond the distance you would use a shotgun, it's a reminder that you should know where you are hitting at longer distances as well as stardard indoor distances.  Some property owners have pole barns or other buildings that exceed 50-75 yards in length.  100 yards may not be "home defense" appropriate, however it may work for buildings and grounds defense.

100 yard zero gives you greater flexibility. It is only 1.5 high at 25, well within what is needed for HD a CQB.

There is some misinformation in this thread.  I would suggest to get yourself to a professional class since online arguments tend to go nowhere. My opinion is to sight in slugs at 50yards.  If you would like then confirm your dope at 100 yards.  Rem reduced slugs do indeed drop about 8" or so at 100 when you have POA/ POI at 50.  This will change depending on the slugs you choose.  By sighting in at 50 yards you will be able to hit very close poa / poi to a bit beyond that distance therefore the only hold over you will need to be concerned about is at long range.  Most shotguns come from the factory set to shoot slugs POA / POI at 100 yards which is why many will shoot high at 50 yards.  I prefer poa / poi at closer range.

Hi,

I know this is an older thread but with my Keltec KSG and Aimpoint red dot zeroing at 25 yards gets me 2" high at 50 yards, and close to dead on at 100 yards.  For closer ranges I hold off the same as an AR-15.

Best Regards:

I'm using Remington Sluggers in 12ga as they group very well and they're pretty cheap. I zero'd at 50 yards as I figure a realistic usage for slugs is about 125 yards max in MOST scenarios. Drop at 100 isn't too bad with a 50 yard zero either so I don't have to hold over too much.

If you zero at 100 you'd be about 2" high at 50. Zeroing at 50 you'll be close to 5 inches low at 100.

Slug zero at 50 yds , and confirm point of impact at 25 yds.  If I hunted I'd also confirm the POI at 100 Yds
Buck , I confirm patterns at all reasonable distances , 7,10, 15, 25 Yds.  ( Vang Comp Barrels)

With stock shims.

25 yards for all uses, regardless of sighting device. A 25 and 50 yard zero with a slug (foster) and the lower sights of a shotgun is identical. The difference is lost to lack of precision even with ragged hole groups, using 0.73" projectiles. At 100 yards on a b27, aim for the juncture of head and neck and hit upper thoracic using 1400fps mv. Using 1200fps, you will hit mid thoracic.

Any resources on shotgun slug velocities?

I'm damn sure i'm not getting what's printed on the box, but as someone who doesn't own a chronograph, it'd be great to have a general idea what's going on.

My choice of slug is the winchester 3" 1oz listed at 1760fps. Cheap, available at any walmart, and groups the best of any foster slug I've tried.

What seems to work for me (with a 9moa RMR) is to zero the cluster high on the dot at 50. The 9moa dot also seems about the pattern size, so it kind of tells me what my hit probability is. By 75yds, the group is low on the dot and aiming for a slightly low head shot at 100 will drop the slug on target.
