wish winchester would make a model 79 extreme weather in 458
22 inch barrel
if I would live in the US I would have one made
buy one in 338 and change barrel have the stock modified for the bigger barrel
but here in Canada good gunsmith are rare and stocktaker

Funny...I have a stainless model 70 338 in an Hs stock that I have considered doing just this...but I just bought a different 458 so will hold of for now...but i like your idea

Great idea !
I have a .338 WIN M70 Extreme Weather put aside for same reason.
Has to be a fluted, stainless barrel to keep with the motif.
So what should the contour be ? That is the question.
The .458 barrel has to be fat enough to flute.
Shilen won't make a stainless .458 barrel less than their #5 sporter.
Krieger uses a different stainless and IIRC, they won't even do them that slim !

Dan Lilja would not flute a stainless .375-caliber barrel of less than their #6 contour.

I noticed that a fluted, stainless, Lilja #6 sporter .375 barrel weighed almost exactly the same as a non-fluted, stainless, PAC-NOR #4.

I wonder if some barrel maker has a .458-cal stainless #6 sporter (or target contour about same weight) that they will flute?

McGowen makes a .458-cal, stainless barrel in their #4 sporter contour.
I consider that as light as feasible on a .458,
McGowen's limit too !
So I wonder what they would consider for fluting in .458-caliber ?

It is not so urgent for me since I have Marcella the .458 WIN-V-3.6" M70 with 23" stainless McGowen #4 barrel.

I will certainly look into the barrel selection, and welcome any comment from sumbuddy who care.

But I might not want to go as short as 22".
Look at Saeed's fluted 26" .375/404J ... it is light.

My M70 EW .338 WIN has a 26" fluted barrel with 0.580" muzzle diameter, 0.600" diameter at 24" length: 6 lbs 14 oz

That would suggest a 24" muzzle diameter of 0.800" for the fluted, stainless .458-cal barrel.
That would look "authoritative."
Yep, plumb bossy.

Rip ...

would the follower be change or use the 338?

what I like about winchester is the cone breach
feed anything no problem

Rip,
The McGowen barrels on my doubles all shoot sub minute of angle. One is .405 and the other is .458.

sounds like a job for 458 AccRel -- not, wait, this has been done, exactly, several times!

The follower on the .338 WIN M70 EW is perfect for a SAAMI .458 WIN.
Tried it on this one:

They have all been great on the many barrels I have from them.
A McGowen is the only barrel I have on a .458 WIN that I would call a true .458" groove diameter.
All the rest are closer to .459".
I must remember to see what the lightest, fluted, stainless barrel is that they will make in .458-caliber.

The best thing about a fluted barrel is you can shave with one, and water your horse on a rainy day! with most of them! Not my cup of tea, but to each his own..Do you know how much weight you shaved by fluting?

Using the PAC-NOR Barrel Weight Calculator,
IF THEY WOULD flute a PAC-NOR Contour No. 6 .458-caliber barrel, you would lop off 0.59 pound = 9.44 ounces.
(17.5"-long flutes, 6 flutes, on a 26" barrel, similar to the M70 Extreme Weather, if flutes start ~6.75" from breech and end ~1.75" from muzzle)

For a sportier 24" barrel, flute length shortens to 15.5" and weight reduction is 0.52 pound = 8.32 ounces.

So about a half pound.

26"-long, No. 6, .458-cal nonfluted = 3.92 lbs/ fluted = 3.33 lbs
24"-long, No. 6, .458-cal nonfluted = 3.74 lbs/ fluted = 3.22 lbs

No. 5 and No. 4 must surely be too light in contour to flute.

24"-long, No. 5, .458-cal nonfluted = 3.37 lbs: Heavier than fluted No. 6
24"-long, No. 4, .458-cal nonfluted = 3.02 lbs: Lighter than a fluted No. 6

Nonfluted: IMHO, a 23"-long No. 4 sporter (less than 3 pounds) is minimum for a .458 WIN.
24" No. 5 is more usual.
McGowen will do their No. 4 in stainless or chrome-moly.
Shilen's minimum is their No. 5.

Krieger probably wouldn't flute a .458-caliber stainless barrel unless it was a straight cylinder from breech to muzzle ... just sayin'.

I also will say that, in my experience, a FLUTED 26"-long Lilja No. 6 contour .375 barrel in stainless
is about the same weight as a NONFLUTED 26"-long Pac-Nor No. 4 contour .375-cal barrel in stainless.
