Thermal scopes and mid-weight calibers will increase your take by twice fold.

You'll be able to stalk in closer and shoot more efficiently versus your current described tools.

That's my two cents

P.S. - you could invite a guy who has that equipment out that lives in the area and can assist in pressuring them a few nights a week...

But, if your overall goal is to reduce the hog population, why not traps?

Hogs are getting a bit out of hand on our place and trying to come up with a more effective technique when hunting (please don't suggest traps and copters).

We typically use 4 wheel drive trucks, spot lights and AR-15's. Hogs are in the open out on our wheat fields. This past weekend we acquired a couple Polaris's with light bars, which give us much better speed and maneuvering, but the rides not smooth enough to use AR's without stopping. Was only able to get 5 pigs before they cleared the field. (one we ran over ) I'm thinking a better option might be 12ga semi-auto with extended mag and buck shot. Anyone use this technique from a moving UTV? Would a red dot or laser make sense on a shotgun in this circumstance? My biggest concern is that 8 shots before reload is gonna limit the damage I can do. If you've used buckshot on hogs let me know your thoughts.

any of the above is not a long term solution

Buy a Sega 12 gauge and two 30 rd drums loaded with 00 buck shot, or regular mags/sticks if you like. Buckshot is hell on pigs in range. I used a 30 rd drum on a Sega 12 and it was a blast.

A big hogs skin is too tough for buckshot unless at a really close distance in my experience. Unless you get an ear shot or lucky spine shot. It will probably kill them, but you'll spend a good amount of time looking for the body. And I don't think I'd shoot slugs from a moving bouncing utv.
