That's something I never thought of , thanks, will probably stop do it, this gun is going to be a lifer for me and I love how they look with a fluted bolt, but will definitely wait for somebody reputable.

Fluting "may" look cool, but in the event of a catastrophic failure the weakening of the bolts integrity can make you look down right ugly.
I don't understand wanting to compromise safety for "looks cool" but is anything but an enhancement to the rifle.
We certainly have the capability to flute bolts but won't due to liability.
So in your OPINION ? or Experience ? do not FLUTE or have Bolts fluted ? Are Factory Fluted bolts in some rifles any different to the same bolt unfluted ? Thanks for a Reply Please .
Cheers Jim
You guys have made rifles with fluted bolts, why the change in heart?

I mean ATRS is a precision rifle manufacturer so I'd assume they know what they're talking about.

Both. Over the 50 plus years I have been involved in this industry I have seen many catastrophic failures or rifles, shotguns and handguns. I have several rather remarkable examples at the shop.
Having been called into court several times as an expert witness has also allowed me to see first hand whats left and more importantly the carnage that a rifle blowing up can create. I have seen everything from the under whelming purposeful destruction of a Lee Enfield rifle where only the rifle was damaged, to full blown destruction where most a persons head was never found and everything in between.
Catastrophic failure is rare for sure, but does happen and for many different reasons. And is impossible to predict when it might rear its ugly head.
When parts are engineered the engineers have to take into account a materials working pressures in all manners, fatigue values etc..
Most factory bolts are not engineered to allow for the changes in structural integrity that may happen due to fluting. Remington 700 bolts are several pieces that are induction brazed together to make 1 operating piece. I have seen bolts where these joints are compromised by being milled through. This can greatly affect the bolts integrity and more importantly how the bolt may or may not contain the blast or how the fractured parts react in the event of a gross over pressure. It is this reason we also refuse to install M16 or Sako style extractors in 700 bolts.
The OP was talking Sako, so the questions then becomes how much safety margin did Sako engineers into their bolts and how much structural integrity is lost if one mills longitudinal slots into the bolt?.
Many custom action makers such as ourselves have increased the thickness of the bolts so as to add structure, but most higher volume manufacturers run just enough material to do the job and not much more.

Look at who made the action. This build was built to the spec of the client and Stiller provided the action complete with the fluted bolt. That has never been a change of heart, we have never fluted a bolt for anyone despite having the tooling and expertise.
Your logic makes sense, I might rethink the idea , but it does look ###y.
I would too AND do ! RJ
Thank YOU for your response - I appreciate your Knowledge BUT have you actually seen a Modern Fluted rifle bolt such as a Rem M700 bolt fail Directly due to it being fluted ? Thxs RJ
I for one have never seen one come apart and have 60 + years around firearms.
The Remington bolt is basically 3 pieces, the handle, the firing pin tube and the bolt head.
The handle is silver soldered on, the bolt head is induction welded to bolt head.
The primary bolt holding is by the two lugs against the receiver lugs.
The back of the bolt floats free not holding anything, the pressure from a round going off is all against the bolt head lugs.
If there is an over pressure there is also a hole in right side of forward area of receiver that lets the pressure exhaust.
Now nothing says you cannot blow up a Remington but it won’t be because you put spiral or straight groves in the bolt body behind the area it was induction welded to bolt head .
In summary the reason for spiral cuts was in case you got dirt in bolt area upon opening and sliding bolt back it would remove any dirt keeping it out of mag well, only other thing is cosmetic

I agree with you - Good Post ! Thxs RJ
RJ, I have seen a .308 Rem that had the case welded to the bolt face and case head separated, the barrel had to be unscrewed and the bolt head drilled out and removed to release bolt body
It only required a new bolt and replace barrel.
Speaks highly of Rem receiver strength .
