Well tests coming soon but here is some logic. A 22 round withholding 130 joules of energy has the same amount of penetration power as a 30mm steel ball with the same amount of energy. But it would cause more damage than a 22 because it has more surface area. Causeing more 6x more damage then a 22 because a 22 bullet is 5mm.
I think you're in for a surprise.
