New to hunting and have a question.

[Double Naught Spy]

I currently have a Leupold VX5HD 3-15x44 scope. Right now I have a few boxes of SST, Barnes VOR-Tx, and ELD-M

Okay, so you have good optics for daylight hunting and unless you are really good, your will probably be limited more by your skill than the optics or ammo. Just saying that you probably aren't going to be shooting 500+ yards, probably.

You have 3 types of ammo that do different things. SSTs tend to break up at shorter distances (higher velocity) using inside 150 yards and out past 200 may tend to act more like a soft point, but one that sheds more weight than a typical soft point. This would be my choice if you just wanted to kill hogs, but not necessarily harvest the meat. The SST and the ELD-M will leave a lot of lead bits in the meat surrounding the wound channel.

The ELD-M (123s, I assume) will come apart more readily at longer distances. Lots of people love these, especially for deer hunting, but also hog and coyote. As a match bullet, I found that they tend to be a more inconsistent in how they perform in the animal in terms of when and how they come apart and to what degree, but they always do come apart and do damage as a result. Of the three options, this would be my second choice if your goal is to just kill hogs.

The Barnes VOR-Tx would be my least favorite choice of the three unless your goal is for a bullet that does not open up very much (but they do open), but penetrates very deeply and will commonly overpenetrate on broadside shots, giving you an entry and exit wound, even at longer distances. A lot of people like this for blood trails, for example. Also, the benefit of this bullet over the others is if you are planning on taking the meat. You won't be worrying about a lot of lead bits polluting your meat.

Those are my opinions. Other people may have equally valid and differing opinions and be able to give you reasons that are as good or better for supporting their views. None of these are bad options.
