"One thing i have done to practice is, at home with an EMPTY gun and bolt out. is close my eyes and get in a comfortable position to shoot.. once comfortable i open my eyes and pay attention to the way my body is and where i am pointed. that way i am not muscling my body in a twisting motion... if im off target i move my feet and not my upper body."
Natural point of aim ,NPA, is important - it is something that takes a good deal of practice and repetition to develop.
"First thing I would recommend for shooting offhand is a good sling you can use to steady/anchor your rifle,..."
The benefit of a sling in offhand is debatable and typically not beneficial if the position has a foundation based on bone structure using the muscles as support and balance. In 3position standing element,silhouette shooting and air rifle slings are not used and to no detriment as the practitioners have developed solid stances through training.
Without support of the arm the sling does virtually nothing - one would be better developing a position with the elbow and upper arm tucked against the side of the body and if possible resting on the hip bone.
However, one also has to ask how much time one wishes to dedicate to the training. To become a really proficient offhand shooter may take months or years depending on the level of proficiency desired.
