Do any of y'all use a 375 Wby? If so, what is your opinion of the round? What model rifle is it in?

I have always had a fancy for a 375 Wby and I might just have one made here soon. Just looking for encouragement.

you could almost call it the .375 H&H Ackley improved.

It gains in real numbers about 150'/sec over the .375 H&H and ammo availability just went to 0.01
(not real good)

Weatherby dumped it for their much more potent .378 and that's a lot more....if you can hack it!

Personally I see it as a dirty trick to pull on a rifle already chambered for the 375 H&H.

I have owned one and, IMO, the round is best utilized to save brass. It won't stretch like the H&H version so your brass life will be very good. Of course, you will be able to get about 10-15% more powder in the case, if that's your desire and velocities will be somewhat higher (so will recoil). A fellow who writes for the Accurate Rifle under the nom de plumme of "DOKTARI" (I believe his name is
Robertson) believes that the factory .375 H&H pushes a 300 gr. bullet too fast for adequate penetration on buffalo and thinks that the factories should load it down to about 2150-2200 FPS for proper penetration. He really prefers the 9.3 X 62 Mauser. I'm sure that people who are as knowledgeable on these topics will take exception to that. I know that Saeed uses a .375/.404 Jeffrey Improved and that is his favorite buffalo killer with velocities matching or exceeding the .378 Weatherby. I do believe, however, that he uses very tough bullets.

Hello Landrum,

I have used the .375 Weatherby for a number of years. It all started with a pair of Weatherby Mark V's my father gave me, a .300 Weatherby and a .257 Weatherby. Next, I tried the .378 Weatherby, but the .378 was too much of a good thing for me. All in all, the .375 H&H did everything I needed, but I wanted something a little different, so, the .375 Weatherby was perfect for me. I look for every opportunity to use my .375 Weatherby whether its power is warranted or not. I'm currently working with the Nosler 260 gr. AccuBond for a "longer" range load. Bullets designed for H&H velocities perform in the Weatherby. I use Norma brass and the Weatherby double radius shoulder feeds nice and smooth.

The .375 Weatherby will produce approximately 200 fps more then the H&H. Not earth shattering, but it does provide for a little flatter trajectory and recoil with scope eye-relief is manageable. H&H's can be shot out of a Weatherby chamber if need be. One thing though, it's a plus if you're a handloader if you go the Weatherby route. You can run a reamer into a factory H&H if yo don't want to go custom.

I have a Remington M700 with a 25" barrel and a Winchester M70 Classic with a 24" barrel.

Good Shooting.

See the reloading pages. Thorough report there by RIP. I have an old M70 rechambered by Weatherby years ago. It is a great cartridge made even better by bullets available today. i.e. Northfork Cup and Flat points. gduffey

I thought you could shoot .375 H&H ammo in a .375 Weatherby, just as you can shoot the parent rounds in all the Ackleys. If that is true, ammo availability is a skosh better than the .375 H&H.

I have one in a fine older CRF FN Mauser action SAKO, built about 1956. It was a 375 H&H, re-chambered to Weatherby. I use it as an elk rifle, and the 260gr Accu Bonds roll out at 2,900 fps using IMR 4064. I use the Norma/Weatherby brass, only.

I've sold two of my three 375 H&H rifles, keeping only my late dad's old Mdl 70. I recently bought a 375 Ruger and like the gun.

Still, my favorite 375...of all I have owned is this SAKO 375 Wby. The case life is very good; I can pump it up to a somewhat flatter shooter with the 260 Noslers for open country shooting, and I have the option of loading it with very heavy bullets at moderate velocities for DG.

The only drawback is ammo availability, which is spotty, but is no worse than many old British NE rounds and can easily be made by fire-forming 375 H&H brass. The 375 Wby would be the last of my 375s to go, if that ever became necessary.

With the 260 Accu Bonds at 2,900 fps (I clocked this many times and have had no high pressure issues) I get the following with a 300 yard zero:

Range: 100yds +3.61" Energy: 4,200
200yds +4.49" 3,515
300yds 0.0 3,103
400yds -10.82" 2,652
500 yds -28.89" 2,259

It makes for a great elk rifle.

My latest dream rifle:

Stuart Satterlee Titanium Magnum Mauser with .700" bolt diameter, and 3.8" box length with .375 H&H bolt face and the magazine box fitted to hold five down in .375 Weatherby.

Then a one pound kevlar, graphite, and fiberglass stock.

And a number 3 sporter contour barrel.

Weight? 6 pounds bare and empty? With scope, sling and 6 rounds of ammo: Less than 8 pounds?

The ultimate rifle for the ultimate cartridge: .375 Weatherby

I have learned that it is easy to load a 300-grain monometal to 2800 fps with a 3.750" COL using H4350 Extreme in a 25" barrel.

The Weatherby factory loads will do 2800 fps with a 300-grain Nosler Partition in a 26" barrel with standard 3.600" COL, and a pressure the same as max .375 H&H pressure.

The .375 Weatherby is the best place to start with a serious hunting rifle, and the best place to end a collection of serious rifles ... for all the reasons stated by fellow forumni above.

Simply the most practical and useful cartridge ever created.

Roy Weatherby's greatest creation: Wasn't it 1944? He was first.
All the other .375 H&H Improved's are imitations of the .375 Weatherby Magnum.

Don't forget to use the new 2001 throat specs. That makes it tops.

From the numbers I have seen, one thing the 375 Weatherby can do nicely is shoot the heavy bullets, 350 and 380 grains (Woodleigh, Rhino), to some nice velocities where the old H&H runs out of steam. IF the H&H is already a very versatile caliber than the Weatherby is more so.

Wink,
That is a good point. As the bullet weight goes up the advantage of the .375 Weatherby over the .375 H&H goes up.

270 grainers: plus 150 fps
300 grainers: plus 200 fps
350 grainers: plus 250 fps or more
380 grainers: ??? never tried 'em
