378 Weatherby-an owners view
      #13325 - 11/04/04 08:54 PM

I have owned a 378 for about 18 years.This rifle has taken
a Northern Territory buff and a Cape buff in the Zambezi valley in my hands and a friend borrowed it to take his
buff on the same trip to Zim in 1991.In 2001 I took a
Win Mod 70 CRF in 416 Rem back to Zim.-it let me down BADLY-I wish I had taken my old friendly 378.
The big Weatherby's cop a lot of flack,I suspect from people who have not used them.I have a number of gripes with my 378 which I will expand upon but in its defence
I would like to make the following points:
The rifle has never failed to feed!!!
it will feed EMPTY cases 99 times out of
100-try that with a mauser!

The rifle is beautifully finished-try saying that about a Winchester.

The 378 is a very powerful cartridge-if the
projectiles are up to the task there is not an animal that
walks that would not be adequately penetrated to the target organ-try saying that about a 458 Win

The action is a very strong one-while shooting some 15 year old well travelled factory ammo
during a summer hunt (temp 110 F in the shade) over a
chrony the velocity exceeded +++ factory listings.The case
head melted into the ejector button and the rifle would not eject the empty round without flicking the case with a stick-try operating at whatever pressure that was with an
09 mauser!
That said I do have some criticisms:
The bedding is sound in design but,like all factory rifles should be attended too ASAP upon purchase.
The two recoil lugs never both bear evenly and I suspect the stories I have heard about the mags. bursting open
and spilling the rounds onto the ground were because neither recoil lug was properly bedded and the mag. well was acting as a recoil lug.

The rifle is MUCH too LIGHT.A heavy barrel and
weighted stock so with scope it should come in at 11 to 12
pounds would allow a rifleman to make accurate use of the cartridges potential trajectory-the rifles recoil in factory trim is much too much for my six foot 3 inch 230 lb
frame to shoot really accurately

The ejection port is small in relation to the cartridge size-it is near impossible in the heat of the moment to recharge the mag. from above.I discovered this as I approached my first buff,now wounded,over open ground.
This was an unguided (no PH back-up) hunt in the NT of Aus.
The rifle was then used as a single shot till the buff went down.The first shot was a good one but the factory 300gr softs back in then were not up to the task.
On the same hunt while bouncing around the back
of a cattle truck I tried to change rounds from the 270 gr
softs to the 300's-as soon as the mag. floorplate was opened the follower parted copany with the follower spring and the whole lot fell into the straw and cowshit on bottom of the truck-my buff was is sight at this point!!!

As mentioned early,if the rifle is subjected to a gross overload in hot weather the ejector can jam up-a flaw
in a DGR
In summary-I still have my 378 occupying a place of pride in the gun cabinet,the 416 Win piece of crap has been
traded off for a CZ550 in 416 Rigby(yet to see if its any good) but the next time I am in Africa it will be with a 500 double I have just ordered from Butch Searcy.Before it turns up I hope to give the 550 a run up in the Northern Territory after buff.
I would love to hear of the experiences of other 378 owners.
Cheers

I have previously owned two of the Made in Japan 378 Deluxes as well as having been directly involved with two other Japanese made 378s. Of the latter two 378s one was one of the few ClassicMarks and the other was an early 1970s rifle.

I have a pair of 378 custom shop upgrades that should get to Nioa Trading by end of May/June.

As to the ballistics I have always simply loved the 375 H&H and to me a 378 is about doing those ballistics with sheer ease (Probably do it with blck powder ) while at the same time knowing you can turn it into a giant 300 Magnum. Often "knowing you can do something" provides the best pleasure.

The Made in Japan rifles have barrels that are far too light and when combined with only average barrel quality and huge freebore they can be very fussy for accuracy. The US Made rifles have the heavier contour barrel, the same contour as the 416 Wby.

Some parts from your posting:

The rifle has never failed to feed!!!
it will feed EMPTY cases 99 times out of
100-try that with a mauser!


That is because of the vertical stack magazine. In addition, feeding empty cases is greatly aided when the calibre has a big chamber diameter in relation to the neck diameter, just like the 378. When all else is equal a staggered magazine feed can never equal the vertical stack for reliable feeding.

The two recoil lugs never both bear evenly and I suspect the stories I have heard about the mags. bursting open
and spilling the rounds onto the ground were because neither recoil lug was properly bedded and the mag. well was acting as a recoil lug.


If the floorplate opens it is not related to the bedding. For one thing the magazine box is quite loose in the 378 based calibres. Secondly, even if only one lug is making contact the other will be only missing contact by thous.

The rifle is MUCH too LIGHT.

Just about everyone agrees with that statement. But the US Made rifles have the heavier barrel and detachable muzzle brake.

The ejection port is small in relation to the cartridge size-it is near impossible in the heat of the moment to recharge the mag. from above.

The vertical stack magazine should be loaded from the bottom. That is, open the floorplate and drop two into the magazine. Many individual 378 based Wbys (30/378, 338/378, 378, 416 and 460 all use the same magazine) will need someone with an iron hand and the strength of superman to load them through the top.

I think the light weight Made in Japan 378s do not recoil....instead they launch a personal attack on the shooter

I just love that statement. I think that I will stick with my 505.

I have a German made Mark V in 300 Wby and I have to agree that the barrel is too light. Also, the length of pull could be a little longer but I find this with almost all rifles.
