No you need to do half grain with a 223, also just touching means you shouldn't feel any more effort to close the bolt, thats jamming the projectile int o the rifling. make up a dummy round, paint the bullet with a black felt tip and carefully chamber. Extract and check for rifling marks, if you have dial calipers measure the lengths of the marks and reduce your overall lenght by that amount.
