Just to definitively rule it out, have you actually had anyone else shoot it and see how they group?
Not suggesting otherwise but you know... Just ticking all the boxes...

I have one rifle with a light barrel and have learnt that 3 shot groups give me more useful results than the traditional 5 shot. Are you shooting from a bench with front & rear support, on a bipod, leaning across the bonnet of the ute? There could be a lot of other variables causing problems.

sorry for the long winded reply

Do u weigh each charge?

Two boxes of 150g factory for break in and sighting in,Sprayed them all over the place ( No better than about 3.5 - 4" groups)
Two full ladder tests later using 150gn Nosler B/Tips and ADI 2208,The results were no better.
Took the rifle of to my gunsmith and this is what he found!!
Bedding job was so tight,The action had to be levered out of the stock.
Rear action screw hole in the stock was bored out of line.
Finish on the crown was very ordinary.
The action was so bound up in the stock,It couldn't shoot.
A realignment of the action screw holes,Pillar bedding job and the crown tidied up and it will now shoot half inch at 100 all day.
Pretty ordinary for a new rifle though,And I do love my Winchesters!!!
