I had a Japanese one and found it better to work with than either the 378 or 460. I think this hada lot to do with the convetnional throat rather than the super long freebore found in the 378 and 460s.
Perhaps it is a victim of the CZ 550 in 416 Rigby.
Mike
It's a nice piece between the 378 and 460,but lacks the super-flat trajectory of the 378,and the enormous power of the 460.
When it comes to a cape buffalo cartridge,it might just about be perfect.For those who can handel the recoil and shoot it well (and are smart enough to shoot premium bullets),it supposedly works like white lightning on most big,mean African game.
I know one thing-I'd sure like to have one!

Out to 300 yards,the 416 Weatherby shoots very flat,but not quite as flat as the 378.Past 300 yards,the 378 leaves it in the dust.
Nickudu,
My dad had a 460 back in the 70s.It'd consistently put three shots into a perfect clover leaf at 100 yards,from the bench.How much more precise do you need?

The difficulty is using this stuff from improvised rests in the field.
I have owned 2 460s and 2 378s plus had very direct involvement with 2 other 378s so I am not without some experience with these calibers.
But I can tell you, that shooting roos and pigs, the 375 H&H eats up the 378 in the field.
Although I think if the 378s would have had KDF brakes on them, it might have been different.
The problem with the big kickers is that you can't just let them sit across a rest the way you do a 270, 30/06 or of course the 375 H&H.
Mike
Just to add to my previous post.
Firstly we have right had drive cars and also shoot from the vehiche.
Many years ago I was shooting a 458 with full loads and 500 Hornadies and was a passenger.
The driver caught sight of a pig that was behind us and just off from the passenger side of the car. I tried to shoot back out through the window at what was obviously a bad angle
Two things occured.
The pig was shot and the rifle flew up and sideways and ended the life of the scope
It appears that the Landcruiser door assembly is stronger than the scope.
That does not happen with the 375.
I know you blokes don't shoot froma vehichle but I will still give you another example.
Try shooting bigger than 375 (remember we are right hand drive) when you are the driver and you rest your rifle on a little sandbag on the side rear vision mirror. And as well, do it several times.
I can give you an iron clad guarantee that if you like shooting big rifles you will have an instant love affair with 375 H&h as compared to bigger calibers and bigger recoil
Mike
Since in these parts we don't hunt or shoot from cars,tree stands,ect.,we don't have to worry about that.
An "improvised field rest" to me is sitting and shooting off my knees.I'd never shoot at anything in the field from the prone position,since I shoot just as steady from the sitting position,which BTW is one of the most comfortable positions to shoot from with a big bore rifle,at least for me.
Also-a 378,416 or 460 with an Accubrake (Weatherby's serious rip off of a KDF)has around the same recoil as a 375 H&H or,for the 460,a 416 Remington.
One more thing-you are right Nickudu,the older 460s with no brakes or the Pendelton De-Kicker could NOT be shot from just about any position other than from the bench or off hand.That's why my dad ended up not hunting much with his,all though he did kill one buck with it with the old style Hornady 350 grain RN (at that point it was very soft compared to todays version with the Interloct)at 2950 FPS.It ended up being a full length body shot from his neck through his pelvis.The only thing salvageable was the hams,and only because the bullet split in two at the pelvis.Talk about meat damage from hydrolic displacement!

The flatshooting ability is depending of the bullet in use.
With a GS Custom HV 330 grs .416" bullet vel in the 416 WBY will be around 3100-3150 f/s - that will leave the .378 FAAAAAAAAAAAAR behind...
------------------
UH
Yards Drop in Inches
100 +3.21
200 +4
300 0
400 -9.39
500 -25.2
600 -48.6
Also note that at 500 yards,it's still going 2144 FPS.
------------------
I'm out to wrong rights,depress the opressed,and generaly make an ass of myself!

You better start eating..
The GS Custom 330 grs .416" HV bullet has better BC than the 260 grs BT bullet, so at long range the .416 will shoot flatter with the bullet mentioned even though muzzlevelocity is 50-100 f/sec lower. Besides the GS HV bullet can be used on really big game up to buff whereas the 378 with 260 grs BT�s will only be a poor deer/mediumsized antilope cartridge....
------------------
UH
Please give me the ballistic coefficient of the GS bullet,and the velocity you will be pushing it.No way on earth it shoots as flat as the 378.
You must not know about big game Nosler Ballistic Tios do ya?They are made with an extra heavy jacket.The 260 grain BT is suitable for all North American game,and everything in Africa short of the hard skins.
------------------
I'm out to wrong rights,depress the opressed,and generaly make an ass of myself!
GS Custom lists a BC of .480 of their .423" (404 Jeff) HV bullet of 320 grs. Unfortunately they do not list the BC of the 330 grs .416 bullet - but it will be even higher (smaller bulletdiameter and 10 grs heavier). I have just mailed Gerard at GS Custom about the specific number.
I can shoot the 330 grs bullet at 3135 f/s (average) with accuracy of 1" at 100 meters from my .416 WBY rifle.
So you better continue eating...
I would NEVER use the Ball Tip 260 grs, .375 on the large antilopes and lion in Africa or brown bear in Alaska (that bullet is only suitable for smaller game and targetshooting - no bonded core , no partition = just a paper bullet)
------------------
UH
First off,I am VERY skeptical about the velocitys you are getting.What length of barrel do you have?Us Yanks are hard pressed to get 2900 FPS from one with a 26 inch barrel with a 350 grain bullet.
You obviously know nothing of the "big game" version of the Ballistic Tips.Please send Nosler an e-mail telling them that all their info is wrong.
A guy posted on here the other day that his buddy shot a musk ox with the 260 grain BT and the ox died (who woulda thunk it?).I'd say it worked pretty good,and a musk ox is a whole lot bigger animal then an elk or most African plains game.

Finally i get to write to you on the net !
I'm the owner of your previous .416 Wby you know, and i go under the "Per577" nickname.
Well, my point is that you get some impressive loads with those 330 grainers,
up to 3150 fps. I'll call you later in the summer, maybe i could come to visit you in Honningsv�g.I must admit that the first thought coming to me was , get those loads, if necessary icould buy a few cartridges to try them out this summer(if possible)
By the way, do you have more info due to A-squares comeback ?
I'm also planning to get me a .505 Gibbs on the big ruger action, and horneber brass for 4 � huntington, i think. That rifle would seriously kick ass !Figure 2900+ with 525 grainers. Or how about buying yours .577 tyr
and all the loads(in my dreams)!!
By the way have you been able to get more than 2715 fps yet ( silly question)and barnes mono solids ????
378 Weatherby,300 grain Siearras
100-+3.39
200-+4.06
300-O
400--9.51
500--25.29
600--48.31
416 Weatherby,330 grain GS
100-+3.39
200-+4.10
300-O
400--9.64
500--25.68
600--49.18
Now of course,we are comparing the 416 to the 378,when the 416 is using the obviously superior GS Custom bullet.Lets see what the 416 does with an "across the counter" bullet-
416 Weatherby,Speer 350 grain Mag-Tip
100-+4.52
200-+5.42
300-0
400--13.3
500--36.52
600--72.31
BUT,what happens when we stick a GS Custom in a 378??Got any numbers handy for one in the 300-320 grain weight?
------------------
I'm out to wrong rights,depress the opressed,and generaly make an ass of myself!

NO - my 577 Tyrannosaur will never be for sale , I�m sorry...
And no I have not acheived more than 2715 f/s with 750 Barnes mono-solid
I will use it in july for buff and I will load it to 2530-2550 f/s to be sure to avoid pressure problems (and recoilproblems..).
If I were you I would build myself a 505 Gibbs or .585 Nyati based on the CZ 550 action - not the Ruger.
But if you load it to 2900 f/s with a 525 grainer then I will NOT shot it - I think pressure will be far to high... ( I know the case is huge but anyway).
------------------
UH
With the GS at 3300 FPS-
100:+2.73
200:+3.38
300:0
400:-7.87
500:-20.81
600:-39.43
With GS at 3435 FPS-
100:+2.45
200:+3.07
300:0
400:-7.21
500:-19.06
600:-36.12
Looks like even if you did gain that much velocity over the Nosler,you basically gain nothing in trajectory-just 10 inches or so at 600 yards,and not enough to worry under 500 yards.

What action did you build yours on. Do people do .577 t-rex's on cz 550 action. Just interested to know. I am currently getting a .585 Nyatti built on a 602 action, my mate is getting one as well. We originally wanted a .577 T-rex but got told it is to difficult. It also seems brass is hard to get for it.
------------------

Ulrik have you got any tricks for coping with the recoil or does it not bother you??.
Have you got mercury recoil reducers in your T-Rex??
