I am going to have to get something that reaches out further than my 12ga.
That depends on your location.
Around my woods, a hundred yards would be a long shot, so the 62gr 109 round should do just fine, even in a sixteen inch barrel.
Too, I trained with, and carried, the A1, so the carbines we have are very familiar. I also happen to like 30 round mags.
Worse comes to worse, out comes the scoped M1A...
Smooth bore 12 ga.? You got some rifled slugs? Or if any of you experts would like to chime in, what round travels farthest for 12 ga?.. By the way, 12 ga. is better than nothing! Also, let the enemy get close so they can watch their friends drop, up close and personal. The thing that would be difficult to overcome is fire. Ya know that in some of our American cities, entire cities will be torched to the ground in massive firestorms. Okay so where do we all meet to fight the bad guys??? Arizona? Utah?..
May I recommend one of these?

A Garand would do the trick and the target will not get up...ever.
Pick up a Mosin Nagant. (I’ve got an M91-30)
7.62 x 54R You can reach out to the next county.
Run ya anywhere between $80 to $200. Military surplus ammo is easy to find and cheap.
Unofficial rule of thumb:
One good rifle, one good shotgun and one good handgun with plenty of ammo for each.
Remington 700... 30.06..big box store,,,can't go wrong. (Mine is .308)
