Polygonal barrel on .300 Win. Mag?

[Menelaos]

Dear all.

I've been thinking of replacing the factory barrel on my Remington 700P (in .300 WM) with a fluted 26 inch heavy bull target polygonal Lothar Walther barrel, 1:10 twist.

The rifle will be used for long range precision rifle competition shooting, past 1000 yards.

As the .300 WM is known to burn up traditionally rifled barrels relatively fast, I was planning on installing a polygonal barrel in stead.

This should (at least theoretically) give me reduced friction, longer barrel life and a bit higher V0.


But are polygonal barrels at all suited for use in .300 WM rifles?

Do any of you have experience with this type of barrels in rifles chambered for magnum rifle cartridges. Is the accuracy better or worse compared to traditional barrels?

Cheers from Denmark.

to get better barrel life,look into meloniting the barrel and action.

Definitely worth a look.

But does no one have experience with polygonal barrels on long range magnum rifles.

not too many folks over here using polygonal except on hk91s

Well.... No one over here does either.

Just got word back from the manufacturer (Lothar Walther).
Even though not as widely used, for extreme long range applications, a polygonal barrel should perform at least as well as a traditionally rifled barrel.

As it won't break the bank, I might just go with it, for the sake of the experiment.
Even found that the melonite could be added at very little extra cost.

Thanks a lot for the input.

Cheers.

melonite will give you much longer barrel life,and if you do the whole rifle,make the action much smoother.let us know what happens

During the weekend I got a message from Gerd Walther of LW, who offered to use my load data to run a computer simulation, to determine the optimal barrel configuration (rifling type, twist, barrel length and weight etc.) for my long range setup.

That is outstanding customer service, in my book.
