Safe Firearm Handling in the Field
Placing the firearm across your chest, rest its action in the bend of your arm. Next, grasp the butt of the firearm with your other hand or cover the trigger guard. It's a very comfortable position. If there is another hunter walking beside you, make sure that each muzzle is pointed in a safe direction.
This takes advantage of the sling attachments on your firearm. Attach a sling, making sure it fits, and place the rifle over your shoulder while grasping the sling with your hand. This is a great carry when traveling over long distances. If you bend over to pick up an object, remember that the muzzle is now pointed in front of you.
Avoid using this carry if you're walking behind someone. For safety's sake, use the two-handed or cradle carry (muzzle pointed to the left or right!).
