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/

for HD I use 25 yrds

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.

100 yds

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

HD 25 yards

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.

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