"Breaking-in" a barrel is bull.......?
Sotry different (for me factory) ammountil you find anaccurate load??
What you are telling me is either you got a "shooter" or not???

One of you please reply with a short list of recommended factory loads(hopefully from past experience).
I have a Remington Model 700 SPS DM .243 Win 26" barrel.
I already had a trigger job done and the barrel lapped.
