The advantage with a shotgun is the wide range of loads available to shoot. The choice of load will depend on the game to take down, different sizes of pellets for small game and slugs or buckshot for larger game.
With the use of shotgun slugs it is possible to take down larger game. Recent developments in design have made the slug more accurate. It is now possible to shoot groups of 2 to 4 inches at 100 yards with 438 grain (1 oz) slugs depending on your rifle, barrel, choke, type of slug, sights and shotshell manufacturer. Since all factors have to be in harmony you will have to do some research on your own to determine the right combinations.
The difference between Rifled Slugs and Sabot Slugs is the accuracy. The ballistic trajectory is more or less the same (because of the difference in muzzle velocity, 1760 fps for rifled slugs and 1450 fps for sabots). If you are interested in ballistics and are working on a PC you can download a free ballistics program from Håvard Skevik.
Mount on sights are available from different manufacturers and are easy to install.

Another advantage is the versatility of a choke system. A choke, the constriction of the muzzle, controls the spread of the shot and enables you to fine-tune your gun and ammunition. You can also use a rifled choke on a smoothbore barrel to take advantage of sabot-slugs and give them the necessary spin.

What is gauge?|
Gauge is the number of spherical lead balls, with the diameter of the bore, that make 1 pound (453.6 grams).
Euh.... as you can see in the calculations below, I'm European.
So the radius of a 12 gauge (# balls = 12) equals
(39.96 / 12*(4/3)*pi)^(1/3) = 0.9264 cm
the diameter is twice the radius
d = 1.853 cm
and 2.54 cm = 1 inch
so your pipe diameter equals 1.853/2.54 = 0.729 inch
Below is a table which gives you the energy of the
projectile related to its weight and velocity. Energies mentioned can be used
for shot and slugs if the muzzle velocity is used.|
Typical velocity for 1 oz birdshot is around 1200 fps, delivering 1400 foot pounds at the muzzle.|
