I believe it is balanced because it is more than enough weaknesses to balance the positives. The fact that the bullet splits in 4 makes the damage penalty feel balanced, I doubt people would actually make the item deal 100 per each bullet and it also doesn't have damage falloff, makig it more important to give a damage penalty so harsh to make it balanced.
