I have done the shot and clean exercise and I have just shoot them. Had a couple of Garands with NEW barrels installed - both had the same manufacture new barrel. On one I used the shoot and clean exercise and on the other I just starting shooting it. Could tell no difference in the two after a couple hundred rounds. HOWEVER, with the Garand there are MANY other varibles that could effect accuracy.
Now, I just play it safe and do the shoot and clean exercise. Can't hurt if you clean properly as stated by SGMJody above.
