With a new gun, I will clean it religously. After 100 or so rounds I back off on the clean after every couple shots routine. Try this sometime, after cleaning as usual, go to the range and shoot your five shots. As you say, it will probably shoot two dead on and the other three 1 1/2" high. LEAVE IT ALONE. Go home or whatever, but do not clean it! Then see if it still shoots 2 on 3 off next trip. I bet it doesn't! What I am saying is that once a barrel is broke in, cleaning with sweets is not neccessary until accuracy starts to deteriate again. I have some rifles that there is hardly any difference between clean and fouled, less than 1/4", and others that take 10 to 15 shots to settle back in after cleaning.
