I have a similar rifle, a .243 ADL Youth model that I swapped out the stock for a full sized camo plastic (factory) stock. I shimmed it up so that the barrel is floated, sanded off the little bumps at the end of the barrel channel, lightened up the trigger to just under 3#. Put a VX 1 3X9 on it in Burris rings and factory bases (tightened up). It will shoot 3) 70gr TNT hollow points into 3/4" or less at 100 yards consistently but I have yet to get 100gr Hornady's to consistently shoot into less than 1 1/2". I picked up some Nosler Ballistic Tip 95gr bullets to try next. I know the rifle is up to the task I just need to find the right load with a heavier deer bullet.
