You've already stated you want a 300WM for hogs. Why? I have no idea. Maybe you like punishment. Maybe it's "cool". Sounds like you don't really want our opinion on calibre for hogs. No matter how much experience we have killing them. Either way, it's your choice. So I guess this thread is more about the rifle choice than the calibre choice.
The Ruger in question is not anywhere near what I would consider a good pig rifle. And I won't just make the comment. I'll back it up with real world, sportsman/hunter reasons.
When hunting hogs, especially in cover, you want a gun that you can have fast follow up/defense shots. Your average, or even above average hunter simply isn't capable of working a bolt fast enough for a charge. Anyone who wants to dispute this, feel free. But working a bolt under duress and reacquiring the target requires too many movements for most people to do quickly and with precision.
Now some may say "Shoot them in the neck and you don't have to worry". They're right. If the hog is alone in a field or you're in a treestand. But when you're on the ground and the "BOOM!!!" (And that gun makes me wince just thinking about it) goes off, pigs scatter. They don't always know where the sound came from. They might all head straight for you. Or only one might. But what about the one that was 30 yards to your right when you shot that you didn't see? And hogs are a lot faster than a lot of hunters think. Especially if they've never encountered one. Something tells me you haven't encountered that many. Not your fault and I may be wrong. If I am, I apologize.
Now to the sights:
Blade/post sights, even if they are hi-viz, are decent for hunting. But IMHO a good hog rifle will either have a quality red-dot or ghost ring sights if hunting in cover from the ground. Again, faster target acquisition.
Here's the positive of that rifle as I see it: Rugers are tough. Decent accuracy. And it's a carbine (kinda).
The negatives: The sights, the bolt, the muzzle break, and the calibre. I'd be willing to wager that if you get that rifle, in that calibre, you will hunt with it for awhile. A short while. Then you will either sell it to get something that is actually better for hogs, your shoulder, and your ears, or you will retire it to your collection and get/take something else.
Now, after all that negativity, I will say that I'm a fan of overkill. I'm a big bore guy. The stuff I shoot is overkill for most things I hunt. But I don't load my guns to max velocities and max bullet weights that kill on both ends. I learned quickly that it's more fun to get my game and save my ears and shoulders.
My opinions are really only worth what you paid for them. But I have killed a pretty fair amount of hogs and I'm just trying to save your hearing, your shoulder, and possibly your life. Remember, big boars are like big bucks. They don't generally run with the crowd. But they might be close, hiding just a little ways away. Need to be prepared.
My last bit of advice. If you get that rifle and take it hunting, and if you shoot at a hog, do NOTHING before chambering another round. And I mean nothing. Don't look at the animal, don't admire your shot, don't blink, don't let your heart beat. Nothing. Pull the trigger, reload.
Good luck on your hunt(s).
