Without making any changes to the gun, have you used a "rear bag". The rear bag goes directly under the heel of the rifle, and should not be filled tight. It should have enough room to move the contents (sand) around, and with your left hand squeezing and manipulating the rear bag that is how you adjust your aim point. The front bag should also not be "tight", but with enough play for the rifle to rest into the bag without moving.

Next is the trigger, less than 3 lb is where you want to be, and considering the type of shooting even less. (If you have to pick the gun up and move with it, keep it in the 3 lb area).

My rifle shooting is primarily Prairie Dogs, range from 50 yards to 500 yards. My 22-250 shoots around a 1/4" at 100 yards. Developing a load to fit your rifle is another entire matter.
