I deliberately disperse ammo all over the place.
4 in the gun with an empty chamber. (I don't load the chamber until I'm ready to shoot an animal.)
A few loose in various pockets.
5 in an external pocket on my day pack.
Some in my clothes bag.
Some in with my food/camp kitchen.
A 20-rd plastic case in my side by side.
Another 20-rd plastic case left in my truck.
While I agree that hunting is not a battle field, carrying upwards of 30+ rds does a couple of things,
1. If I lose a pack or bag, I haven't lost all of my ammo.
2. If my rifle take a serious drop, I have enough to check/reset zero on my scope.
I've never viewed my rifle as a repeater; the magazine just holds additional ammo, not multiple shots on the same animal.
