Ya...I am shooting 350 gr. Speer and 350 gr. TSX out of my .458 for hunting at home. Using AA2230 and pushing them along at just over 2,450 fps. I could no doubt get a wee bit more velocity but there is no point. Both bullets shoot nice tight groups and they are putting out more than enough horsepower for anything I pull the trigger on here...which is usually bear and they are always DRT with a bounce. Certainly do not need to use it here either but the only way to stay completely familiar with it is to pack it around hunting at home.
