I usually pack about 10-15 ronnds, my tags, extra gloves, a knife, and a few snacks.

i don't really know what you mean by walking but when i'm deer hunting: a full magazine of whatever gun im carrying, a knife, cell phone, an extra sweatshirt, canteen, and some snacks all wadded up in a nice little backpack.

if you mean just going for a walk, my cell phone and a house key
