What are some techniques you all use to increase your offhand accuracy that can be done without shooting? My rifle is balanced about 1/3 of the way up the barrel so if I tuck my arm in tight into my chest, it is front heavy and I'm not as accurate as when I hold it on the balance point. I've thought of just practicing holding the rifle on a spot on the wall or even tying a little weight on the center point to make the rifle slightly heavier as a little "workout" to improve muscle strength.
