I have never left home without the rifle having a sling attached. Slings are for Shooting. Secondary for carry.
This is how I carried my rifle in the field, every step of the way. It is far more comfortable than you might think, and you keep 100% control of your rifle all of the time.
You can give the other arm a rest from time to time as well.........
The rifle is already in position for shooting, and stability...........
Above is what I would call double wrapped, extremely stable with my off arm going over the sling and to the rifle...........
Below is without that.........
Getting on sticks is not a problem, just practice a few times like anything else............
It is hard to see in this photo, but I definitely have that sling wrapped and using it for stability....... dead steady........
Can't see it, using the sling on the off side, and a tree on the right to keep steady...........
And again they are taking photos from the right side, but I am again wrapped in the sling for this series of shots........
And yes, on occasion one can even take a break, use the sling like this...............
If you do not use a sling to shoot, give it a try sometime, and I think you will find your rifle is far more steady, you are able to get on target and stay on target easier, longer, and the sling will be a great aid in controlling your rifle during recoil as well. Basically the sling gives you more control over your area used properly. What I have shown you is what works for me when I was in the field, there may be little tweaks that make it easier for you. I have never suffered any of the other issues that some bring up like getting hung up in brush or what have you, and I have been in the thick stuff many times, and rifle has always had a sling.
Even on very serious Dangerous Game Hunts, I always use a sling................
