At one time I would have said Remington, especially the 40x. The mod 600 and 788 were unbelieveablly accurate. Now from what I,ve seen from other's rifle's I've loaded for, Savage. Also read just a few new deal's that's intresting, not willing to take the plunge yet tho, does Mossberg ring a bell?
Without my present disgust's interfering, the most accurate rifle's I,ve owned; Remington(rest in peace!) and at #1 Sako( the old L61R, L57 and L461.
