I have a couple of suggestions, things that worked for the most part with my kids. I suggest a set of front a rear sand bags. I prefer the 'Owl ear' type in the front and a set of large 'bunny' ear in the rear. The owl ear bag has a rounded profile notch for the forearm to lie in, while the rabbit ear or bunny ear bag has a 'V' notch stryle of ears which allow you to lay the rifle on the bags. Making the final adjustments to get the sights on the target by squeezing the ears on the rear bag to raise the rear of the rifle, lowering the sights on the target.. When properly used there is almost no movement of the sights on the target. The butt must remain in contact with the shoulder and when you wish to fire, instead of trying to pull the trigger, try pinching the stock. That is pinch the wrist of the stock between the thumb and index finger of the hand on the controls. The other hand is curled under the rifle and is maintaining the pressure on the rear bag that is holding the rifle on the target. The front of the rifle is totally supported by the front bad. Also another trick we used was what I call 'good gun, bad gun'. Start the day with a rifle with a rather poor trigger. Something that shoots OK but the trigger pull is rough, heavy, gritty, etc. I used an SKS(chinese) for my daughter. She shot the SKS untill she learned to manage the terrible trigger. The SKS was fairly accurate and at 50 yards she learned to control the trigger quite well. recoil is pratically nothing and ear/eye protection is ALWAYS worn!!!! At the end of the day we switched to a Remington(any brand is OK) 700. This was an old and trusted friend, in 243 Winchester. I'de used the rifle for years and new what it could do. The trigger was clean and just a shade under 3 pounds, no over travel and no slack. After fighting the SKS's trigger all after noon the Remington's was a blessing.. She immediately could shoot amazingly small groups at 100 yards. After doing this a few times we introduced shooting of an improvised rest. That is she learned to us a lean up, post tree anything to rest against to help steady her aim. We used the SKS and it's cheap ammo served us well again. When she's learned to control that miserable SKS trigger and shoot good 50 groups she swittched to the M700 again and 100 yards and under an inch and a half was not problem. She's killed close to a dozen deer now with a single shot each.. Some with the 243, the rest with a 280 I built for her. College limits her hunting time but she knows how to shoot.. Technique is everything. Practice is only good if you're practicing good habits. A truck or vehicle is never the best thing to shoot from. Speak with someone from the local gun club. I'll bet there is someone there who will help you learn the correct way to shoot... and Good luck.. As the good colonel said, only accurate guns are truly interesting!
