I would stay with the 158 grain in the 357 magnum, especially if shooting jacketed bullets. None of the 180 grain jacketed bullets I load can reach the speed and energy of the 158 grain bullet.
Now having said that, if you go to a cast bullet such as the RD 190 grain TLC-FP at 18-20 BHN or the Cast performance 180 grain WFN/GC, you can push these up to about 1600 fps. That is still below book energy levels of the Jacketed 158 grain but it will penetrate deeper on a big hog, especially if it is a shoulder hit. The problem with the bigger bullets and a Marlin is having to seat then deep enough for a proper COL and that just doesn't leave much powder space.
