    IMO, the shoot one shot then clean method does more harm than good. Shoot a 20 rounds of ammo to get the scope zeroed, and see how it does out of the box, then give it a good thorough cleaning. After that, just shoot it normally and don't over heat the barrel. Here is a good write-up on break in at Sniper's Hide.
