So you got lucky
the one 3 feathers brought might shoot 1/2" groups if you consider 20 yards a suitable distance.
Sad but after a long time trying and loads of ammunition shot and tried the Model 7 that 3 feathers has will sometimes shoot a 2" group mostly if I read his original post correctly it's larger.
Of course he could have wasted more time sending the rifle back to Remington but as it will shoot a " groups with some ammunition then it meets their acceptance standard so that would be a waste of time and more money for the shipping.
Just enjoy yours and reflect just how lucky you are that yours shoots as well as it does.
