I am new to muzzleloading and have not even shot my ML yet. As we speak right now I have my ML at the gunsmith's shop to have a scope put on, and boresighted. I do however have experience shooting long distance. While in the Marine Corps, my weapon that I was taught with was the M-16A2. We were taught to shoot 200, 300, and 500 meters. At the 200 meter line, we would have to shoot offhand. What was taught to all Marines was to use the sling. Take your sling that you have on your ML rifle and wrap it once or twice around your arm. Take your arm that you have wrapped in the sling and tuck it into your body. With the sling wrapped and your arm tucked this provides pressure to your weapon into your body--which will provide a more stable base to support your weapon. I have been out for a decade, but the training still stays with me today. This also worked for me when I would fire my M-249 SAW in the offhand position.

I know that the ML you have is not the same as the M-16 or light machine gun, but the principles are still the same.
