A hard cast Keith style semi wadcutter of around 245 grains should do well in the .44 mag.
I like to stay around the 250 grain mark, just because the recoil is lighter - but for the larger hogs I find you really need a heavy bullet to do the work. In my 6” barrel 629, the 300+ grains get the job done but the gun does ‘talk’ to you. I also wouldn’t shoot them any more than needed as I’m pretty sure they would loosen the gun up.
