barrel flute timing

I recently read that when you flute a barrel it must be set to the reciever with the a flute top dead center for timing? Some gunsmith's do this and some do not so you should specify if you would like it done this way or not. Can someone enlighten me on this?

The flute has to go on top so the scope can fit closest to the barrel. Or maybe a rib should be on top with a flute on either side to minimize gravitational barrel sag. Most likely it makes no detectable difference how fluting is oriented and it's purely cosmetic. Most fluting jobs are cosmetic. In my opinion better barrel rigidity for the weight can be achieved by proper contouring than by fluting a cylindrical barrel. Here's an example of tapering combined with fluting which makes some sense though it's not pretty. I believe this is a 25mm barrel for a Bradley vehicle.

Re: barrel flute timing

Alignment or timing of the flute is probably important if you are reusing a factory barrel due to the writing that is engrageved or punched onto it...the caliber and make etc...

Also, I have given thought to a mountain rifle with fluting for weight reduction but with open sites as well. I never completely trust a scope.....

It would be therefore necessary to align/time the fluting to allow a solid surface on the top of the barrel.

Nott sure how you would specify these things other than to communicate fully with the GS.

It does not make any difference where the flute or rib is placed as far as accuracy but from
a cosmetic standpoint it must be timed with one or the other on top or it will look bad.

I like to time them so the rib is at the stock line and not the grove so it fits the stock
better so depending on the number of flutes you will end up with a rib or a flute on
top.

A good gunsmith will always time the fluting any way you want it.

Re: barrel flute timing

Very easy answer----On my competition rifles it is done that way so when I change tubes in the field there are no problems period. The way Speedy cuts the threads when it locks up it is as tight as a tick!

Has anyone been laughed at by a deer or elk because their fluting wasn't properly timed? I have 300 Win Mag Sendero with the printing on it's fluted barrel upside down on the right side.

I know what it takes to rotate the barrel 120 degrees which is why I didn't. I might care if I'd just paid a gunsmith $850 to install a custom fluted barrel but I only gave some guy on ebay $85 for a factory takeoff.

The shame of possibly hearing "My rifle has a better timed barrel than your rifle." is not something I'm going to loose sleep over.

I detect a little sarcasm ,but I am not thin skinned and believe it only matters to some ,
but I still think it looks like s#!T if it is not timed properly just like a brake that is not timed.

I have seen rifles that were not timed and to me it was a reflection on the smiths standards
and attention to detail and if he won't take the time to do it right what else has he not
done right?

But you are right about the Elk and deer not caring ,but some "people" do.
