Fluting change accuracy?

Alright I understand barrel harmonics etc, but looking for someone with experience if i send a barrel off to get fluted to shed weight will it change the accuracy a lot(new load development)or just a little. Shoots in the .2

In theory, the bore can open up a little due to cutting flutes. But from my own experience I have not found a drop in accuracy in very accurate rifles after a barrel is fluted. I have sent match grade barrels off to get fluted, then shot them in competition and long range hunting rifles and they have shot very well. In some cases I have placed with seconds and thirds in national level shooting competition with barrels that I have had fluted.

For what its worth, I have always used straight flutes. I Dont know that another pattern like say spiral fluting would cause a problem, but cant say from first had experience. I think as long as the barrel is well stress relieved to begin with, you should be okay.
