How quickly the shot disperses is almost entirely a function of the choke, not the barrel length. The OP's shorter barrel has a more open choke, so it will disperse the shot faster because of the choke, not the length. Not that it will make a lot of difference at home defense distances.

The biggest advantage of the shorter barrel for HD is that it's shorter. 26" is longer than ideal for HD; 30" would just be too much to move around inside.

You are correct. As far as I know, the 26" barrels are primarily set with no choke, making the shot disperse wider. The longer barrels are usually set up with a modified choke and as you said, swinging another 4" is just a tad cumbersome for my liking.

yes the longer barrel makes it odder to carry inside but im on the farm and in a shtf scenrio i may have to use it outside also so if the 30 inch gives me a few more feet of lethal range id take

Without knowing the choke on the 30" barrel, your best bet is to take the gun to a range and test different distances where most of the shot is confined within the size of an average person's torso.

For dove, quail, pheasant, turkey, etc. 40 yards more or less depending on shot size.

For buckshot on deer ~50 yards.


On the imp. cylinder 30 yards is the generally accepted cutoff point.

Default Mossberg 12 guage

I was out at the range and shot my Mossberg 500 with 18-1/2" barrel at 25 yards. The buckshot spread out more than 24" at that distance. Beyond that I am not sure what I was shooting at would actually get hit with any pellets.

Your 18.5" barrel undoubtedly has a cylinder choke. It's designed for HD distances, which would realistically be less than a third of the distance tested. Inside your house 25 feet is a very long shot.

If you really need to engage targets past 25 yards get a rifle.

The overall length of the barrel has little to do with the pattern. Longer barrels are better suited for dove/quail/duck/skeet because of the swing. Shorter barrels are better for turkey/HD to minimize movement in the field and to negotiate hallways easier.

Pattern is controlled by the choke. The OP stated he has a 26" barrel with a fixed skeet/IC choke, and a 30" barrel with full choke. Neither of these are good for HD. The Mossberg 500 12 gauge is an ideal platform for HD, you just need the right barrel. I would get an 18.5" cylinder bore barrel and call it a day.

Mossberg (90015) 500 18.5" 12 Ga. Barrel

If you don't want to spend the money on another barrel. I would have the 26" fixed skeet/IC cut down. The legal limit is 18"... Mossberg goes 18.5" just to be safe. Another option is to have it cut to 22" and threaded for screw-in chokes. Then you have choices.

Here is another school of thought. You don’t want a ton of spread in HD situations. In short reason being is control of every last pellet. Meaning the more flyers the less pellets on target and the more pellets penetrating walls and possibly hitting loved ones or neighbors, bystanders. Also the choke is not the only thing that controls pattern of your shot. As far as the barrel it’s a combination of forcing cone, actual bore size and choke as a team… Then there is the shell its self. Hardness of the pellet, wad construction and velocity all are big players in the final pattern size, especially the wad. Look up testing on Federal FlightControl 00 buck. A shotgun needs to be aimed like any other weapon and just isn’t an instant kill when you point it down the hall.
