No, I'm not saying if you go out right now and shoot a leaf with a 0.20 it will bounce off, I'm saying in a situation where the 0.20 will bounce off, the 0.25 has a much higher chance of punching through.
This is due to the monentum and the force the bb has. The mass is directly proportional to the momentum and force. The more mass it has the more ability it wil have to break through leaves and twigs.
