break in
aerod1,
Here is my break-in routine:
1) clean rifle (make sure the chamber and bore are dry)
2) throw as much lead down range as possible
Followed this routine with all my rifles, including my AR15 service rifle (which I will most likely never compete with). All my rifles shoot great, and my service rifle and HK SL8-1 are both tack-drivers.
Your mileage may vary.
