I have 18 years of hunting under my belt. 10 of which is rough style camping in woods fir 1-2 weeks. We brought no food only water. We ate when we shot our meals for the day.
I dont need guns to survive, i have my trusty leatherman tool,machette and smith and wesson pocket knife. The guns just give the extra edge on protection to stop threats long range before giving up your loaction when their right ontop of you. And close range the knife is your best friend to stay out of sight.
Also dont fotget my compound bow as well as crossbow.
