Fluting change accuracy?

[Aaronjazek]

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.

Might check with the barrel manufacturer to see if they have any info.

Typically cut blanks tend to not move. Broached blanks can release some stress. Size matters....and the likelihood of it shooting measurably worse is pretty low for most guys....but you have a special rifle if it shoots in the 2's.

Thanks all, I actually just bought it. Saum built on a long action, it's in a chassis, has a heavy contour from pictures, I was just going to have it fluted to shed weight and throw it in a light stock but I can't say it's even worth it with how much I pack a rifle (never) usually just ML or bow. Thanks everyone for chiming in
