Walking rifle to me would be a Pennsilvania flintlock long rifle. Preferably in .45. Load it to whatever level you need for whatever you encounter along the way.
No reason not to carry a touch of nastalgic class when walking in the woods.
If your in a war, instead of throwing a hand grenade at the enemy, throw one of those small pumpkins. Maybe it'll make everyone think how stupid war is, and while they are thinking, you can throw a real hand grenade at them. www.sendoutcards.com
