Depends on what I'm doing and who I am with. If I am using the "sit and wait" method, I will have a round chambered. If I am "running and gunning", and hunting with other hunters, the chamber will be kept empty until a gobbler is struck. If I am by myself, I sometimes will carry a round in the chamber, unless the terrain is difficult enough that I think there are safety issues. Here is some food for thought.
Decades ago, I learned a valuable and lucky lesson about carrying a loaded gun in the woods. I was alone, and several miles back in the Gila Wilderness, descending a steep slope headed towards a distant gobble I had heard. I was hurrying along, trying to cut the distance to the gobbler as quickly as I could, carrying my old reliable Model 12. I had the gun firmly (I thought) in one hand as I scrambled down the hillside, using the other hand to help keep my balance as I went.
I was a lot younger then and, of course, thought I was indestructable, so I always carried a chambered round, thinking that there would come a time when I would not have that split second needed to pump a shell into the gun. Anyway, as I clambered down the hill, I hit a patch of dry pine needles covering some loose soil. Instantly, both feet went out from underneath me so suddenly that my gun-carrying hand jerked violently upward, sending the shotgun airborn like a twirling baton.
As I landed on my back, I watched the gun, seemingly in slow motion, as it made a couple of quick cartwheels and then headed back to earth six feet below me and landed sharply and solidly on it's butt, with the business end pointed straight at me. Fortunately, I heard the dull thud that followed, as the gun harmelessly came to a rest. Chills went instantaneously up my spine as I realized just how close I had been to spending my eternity sprawled out dead on that remote canyon hillside.
To this day, thirty years later, I can still see that shotgun spinning in mid-air in front of me, and the feeling of helplessness I felt as it hit the ground.
I learned a priceless lesson on that day. No matter how competent one thinks he is with a weapon, nor how safety conscious, things can happen in the blink of an eye that can change lives, and the living, forever. Each of us should think often about the possible consequences of carrying a loaded weapon in instances where it really is not necessary, and especially when there are multiple individuals involved.
