I do have a solid retort.
I'll answer you since you don't know and unlike basketcase, he refuses to do any research and you don't have a track record of that.
AR15's are extremely popular for hog hunting, in the 5.56/223 caliber as well as other calibers like 300 Blackout which the AR15 can be easily converted to as all you need to do is switch the upper. 5.56 is still sufficient in most cases because you can get up to a 77 grain bullet in that caliber that gives you plenty of knock down power vs the original 55 gr that they used in Vietnam. It is not as common in North America to have a separate upper because guns are cheap here, but in Europe and other parts of the world, it is because only the receiver that contains the firing mechanism that is considered the gun. In addition to being very good eating, hogs are very destructive and the government, both American and Canadian wants them eradicated as they cause an estimated $1.5 billion annually worth of damage.
The reason for using semi automatic is because hogs are herd animals, so having the ability to follow up quickly means you have the ability to take down a large number of them. Very beneficial when you are trying to eradicate them.

The AR15 is also very good for hunting prairie dogs, which are prolific and are also very damaging. It is not unheard of to shoot over 1,000 of them on one property on a weekend. Farmers love it when hunters get rid of these because not only are they bad for crops, their holes cause injury to horses and livestock like diary.
What makes the AR15 good for hunting vs other types of semi autos is because the direct impingement action with the buffer results in smoother recoil, so faster follow up shots.
Those are the facts.
