If you're using a 358 Winchester I would go with the lighter bullets, either the 200 grain Barnes or the 225 Partition.
If you were using a larger round - 35 Whelen, 350 Remington Magnum, 358 Norma or STW, I would suggest a heavier bullet.
Way back in the 1980s the late Finn Aagaard reported good performance with the 250 grain Speer in his Whelen.
