I shoot a bunch of hogs every year, and have used just about everything to do so. The 25 is my girl, but the lighter bullets just aren't as reliable for putting them on the ground. If I were to suggest a weight bullet I would not go any lighter than the 115gr. I normally run the 115gr Partition as I can get decent velocity to go along with the weight. The 120's w0uld be good, but your probably going to find a better selection of 115 and 117s to choose from.
My daughter has my original 25 now and was shooting the 110gr Accubonds. They group crazy tight out to as far as you want to shoo them, but they lack the weight to reliably put a hog down. I have shot several with them and IF you can put it in their ear your good, but on a heat lung shot they can tote them off into the brush. I have had a few tote off the 115's but not from a decent hit.
Right now I am running a 25-06 AI and using the 120gr bullets in it. That is a bit of a different critter than my standard version as I can easily get better velocity from the 120's in it with it's 28" barrel than I can the 100's in the standard version. It will put a fat hog down with authority.
Within the ranges your looking at however and even a bit further, the 115-117's will give you a bit flatter shot and should have plenty of put on down reliably. Just keep in mind, a hogs built a bit different than deer and such. Their vitals are up front and right behind the leg. A shot behind the shoulder is a shot in the paunch and they will leave little to no blood when they take off. Here is a great site that will get you everything you need on putting them in the freezer,
HUNTERS ANATOMY OF A FERAL HOG
This is one of the best laid out anatomy pages I have seen. There is also other things there in the Tip and Tricks section that will show the best places to shoot them for a quick recovery.
Good luck, and hope this helps.
