the earth hit my head. stop being a pusillanimous individual walnuts cant cause K.O
If hit right.
And I don't think you people know what I'm talking about when I say walnuts in their shell.
I'm talking about these

They can be big or small, it depends on how long they grow.
We use the big ones with a thick shell and until they dry up they aren't soft at all.
@ Dez, just forget off. You can't act like you know something until you've actually experienced something.
I've seen both Painball bruises and Walnut(still green and hard) bruises.
A walnut bruise is a bit bigger.
And a Airsoft gun pfft, those things don't leave much but a sting.
