Why no 375 RUM?

[Riflecrank]

I know there is plenty of hate here for the Weatherby cartridges like 378, 416 and 460 but why does no one talk about or use the 375 RUM? What I've seen looks like it runs on the heels of the 378W, is it to much kick? Lack of availability? Just curious.

I have tried them all that you mention and too many more to shake a stick at.
Always, the .458 Winchester Magnum is the winner, with a 3.6" magazine box it beats the SAAMI .458 Lott.

My .375 RUM affliction was short-circuited by the more practical .375 Weatherby Magnum of 2001 CIP.
That is the best .375 of all, able to fire common .375 H&H in a pinch, accurate and only loses a hundred fps in the roomier chamber. It gentles the .375 H&H recoil for the sensitive-shouldered.
Yet it can do 2800 fps in a 26" barrel with 300-gr Weatherby factory ammo.
Just what a .375 RUM is touted for.
I have also tried .375/.338 Lapua Magnum (aka 9.5mm Tornado),
.375/404 Jeffery,
.378 Weatherby Magnum,
.375 Ruger.

None offer any advantage over the .375 Weatherby Magnum,
except the .375 Ruger's compactness at lesser MV,
and the .378 WbyMag's greater MV at all kinds of disadvantages.

In my fling with the .375 RUM in 2001, I shot a nice big buck from a tree stand
(I was in the tree stand, not the buck)
with this 23"-barreled one that was faster and more accurate than the Remington factory rifle
having 26" stainless barrel (M700 LSS).
Same 300-gr Swift/Remington factory ammo used in both rifles and on the white tail buck:

Great looking rifle and fine shootin, do you still have it?

Axle2010,

Thanks for the flowers. Sorry for the tardy reply.
I have been busy collecting and shooting more .458 Winchester Magnum rifles.

I have the take-off .375 RUM-marked barrel (not marred by take-off) and the unique custom stock that was fitted to it.
The striking CZ 550 Magnum action (with no billboard marking on the left side, serial # AHR 50,001)
is currently sitting in a CZ "Kevlar" stock from CZ-USA ...
(Trademark infringement made them change stock model name to "Aramid" before they quit selling the very same B&C stock for $200 more than cost from B&C directly)
... and that action has a Dan Lilja, stainless, fluted, No. 6 Sporter contour, 26" long, 1:12" twist, 6-groove barrel screwed into it.
That barrel was chambered for .375/404 Jeffery with latest revision CIP .375 WbyMag throat on it, from a custom reamer made by Dave Manson.
Basically a .416 Dakota necked down to .375 and throated to my specifications.

I need to turn that special CZ action, Winchester barrel, and custom stock back into a .375 RUM WinCZeckster with 23" barrel, now that I have a plan for the fluted, fat Dan Lilja barrel.
I also have a No. 4 McGowen take-off, stainless barrel in .375/404 Jeffery that is only 25" long and 1:10" twist, and weighs about same as the No. 6, fluted Dan Lilja.
Re-chambering the Dan Lilja to something racier is now indicated.
I also have a .410/404 Jeffery Rimless Nitro Express on a CZ 550 Magnum action in a B&C Medalist stock. That rifle is about as desirable as tits on a boar hog.

The Dan Lilja .375 barrel would make a dandy .375 CheyTac on another CZ 550 Magnum action.
I have proven that the Dan Lilja No. 6 sporter can be made to fit in the B&C "Medalist" (best model name for it) stock for the CZ 550 Magnum action.
Use stubby bullets for feeding through the magazine.
Single load the long and pointy ones for King of Two Mile.
I also have a CZ 550 Magnum .505 Gibbs, whacky first year production,
and an MRC M1999 PH stainless .408 CheyTac sporter with a Dan Lilja No. 7 Sporter, stainless, fluted,
1:13" barrel, of 26" length. Barrel too big for a B&C, it is in a Plain Jane walnut stock supplied by MRC.

Creating a .375 CheyTac sporter on a CZ 550 Magnum action is indeed feasible and will goad me into re-assembling the .375 RUM WinCZeckster.
