You absolutely have enough gun and bullet for hogs. The thing is where you hit it. From the sounds of it, you probably hit through the onside shoulder and the bullet lodged under the offside shoulder, or you went high through the abdomen.
The fat and hide on them will plug the hole up a lot of times in the mid sections, an not allow much of a blood trail, same issue with only one sided penetration. The hide or surrounding fat will cover up the entry hole and not allow them to bleed.
I use a Ruger Compact and 150gr Remington Cl's for about 98% of my hog hunting with a rifle. Most times, unless it is a head shot or a smaller hog, I do not get much of a blood trail even with a complete pass through.
For heart and lung shots most folks shoot too far back on hogs, their kill zone is more forward than other critters.

I had a similar experience to your last Thanksgiving. I got on two sows that were roughly 200# each and busted them out of their beds. The first broke out across an open cotton field, the other broke right and into a ditch out of sight. I swung, centered, and fired on the one in the cotton field rolling it head over hind end into a dusty flop. The second came out of the ditch about 50 yards down and caught the second round in behind the right shoulder and out through the front of the left drooping instantly as well. As I walked over to the first, there was nothing there. No hair, blood, and anything but a big scuff mark in the dirt where it hit and rolled. Looked for it for close to an hour and still nothing. Loaded up the second and headed in. Back in February, I was over there again with my 454, and walked up on another pack in their beds. Got two right off the bat before they even got to threir feet, and another on it's way out. When we loaded the second one up there was something about that just wasn't right. Upon further inspection, we found close to a 12" gash down the top of it's back, right along the side of the spine. Turned out to be the one I hit back in Nov. that had made it fine up till then. The wound was still not completely healed and had some infection so we decided to forgo anything further. Still it goes to show how tough and resilient a critter they are.
