Penetration Vs Infanty

Had a question come up in a game recently. Was shooting a Anti-tank Rifle at a group of enemy infantry. The enemy were past 24 inches but within 48. When rolling to wound, does the anti-tank rifle get +2 to wound because it has normally a +2 penetration, or does it only get a +1 for being over half range like it would shooting at a vehicle?

Oh and a pic of my Team just because.
