Your next session of load development try the following at the range. Double bag the Garandicon. One bag under buttstock. Front bag one to two inches in front of trigger group plate. Do not put a bag under or in contact with the front hand guard section. Completely remove the sing from the rifle if one is installed. Do not force the rifle down into the bags while you fire. Then shoot five round group for size. On some rifles you need to disregard the first shot as it was not loaded by the rifles full function cycle and it may be way out side the group you will get from rounds 2, 3, 4, 5, 6. problems like this can be corrected later after you have found a load the rifle likes. Good luck.
