Almost impossible to say for certain. The caliber is not the determinant, the particular barrel is.
Some barrels like light bullets and shoot them most accurately.
Others like heavy bullets and they shoot them most accurately.

I have two Savage .308s with 24-inch barrels.
One shoots 155 gr bullets best and the other shoots 175 gr and heavier bullet best.
I would have bet that they would shoot just about the same.

The only way you'll ever really know is to try it with the 125 gr bullets.

My .30-06s like H4350 powder the best, but they also shoot other powders almost as well.
With the scarcity of powder these days, you may be shooting what you can get your hands on.
