New rifle, did I screw up?

I have a friend that has the 770 in 30-06 has had no issues with it.  I bought my wife same rifle in .243 changed out the stock scope and it is very accurate.  We have not had a problem with ours.  I've also have a rem 710 for years with no issues.

Last night I talked to a friend of mine who has one. He said good scope and he can drive nails at 200 & 300 yards all day
