Of the 30 mags the WBY shoots the flatest and hitts the hardest, even if only by a bit. Not counting Ultra Mags and other big big ones

So why would you not count the ultramags,brass is the same price and factory loads are cheaper than the weatherby factory loads.And remington rifles are lower priced.
 
300 Wthby

The 300 weatherby doesn't start paying it's way until you get up to 220 gr.bullets. The 300 win is basically winchester's shorter version of the 300 H&H. The 300 wthby is a blown out 300 H&H case. All three ,basically use the 375 H&H case. The 300 H&H is the most efficient on powder. To get 100 or 200 fps more you use quite a bit more powder. The only disadvantage the 300win has is the short case neck; but bullets seated properly don't pose a problem. Lots of practice and shot placement will of course be the real difference. By the way ---- Craig Boddington has worked out a good load for the 300 H&H ----- 74 gr 4350 pushing a 150 gr bullet at 3400 fps -----

The original question was about the WBY, Win and WSM. The ultra is still more no doubt and cost of components dosen't really matter as cases don't have to be WBY headstamp. The Ultra would have a slight advantage over the others and the 30-378 still more.

And 30-378 brass is very expensive compared to the ultramag brass.You also have to buy an overpriced weatherby rifle to shoot the 30-378.The costs and components of the 300wby and 300ultramag are simularly priced.However non weatherby factory loads for the 300wby are downloaded considerably compared to the very expensive weathery loads.This is a factor if you don't handload.
 
Weatherby

I have owned several Weatherby Vanguards. All shot sub-moa and all are reasonably priced.

Is there an big advantage of a 300 wby over a 300 win mag, no. But there is an advantage and if you handload you can add the extra 5 grains of powder and take that advantage, or load closer to minimum and 300 win mag specs. Also brass for 300 wby can be purchased from Remington.

My favorite Wby was the 257 Weatherby for deer. A definate advantage over a 25-06, and the hype of Weatherby cartridges is not overrated. The penetration of a 120gr Nosler partition with a 257 is phenomenal.
 
the 300 WBY has the same advantage over the 300 win that the 30/06 has over the 308win about 100fps.the advantage the 300 wby has is it can drive the 200gr premium bullets at 3000fps and the 220gr bullets at 2800 fps.Is it earth shattering no,but so what .It's fun to play with. Enjoy all our chioces and have fun with them.Will it make a difference on game , who knows but who cares it's fun to discuss it!
 
I owned a 300 Wby, and was never able to get more than 25f/s advantage over my 300 Win mag with the same bullets and the same barrel length. It is a great long range killer of game, and when matched with the right rifle and shooter, is a lethal unit. In a light contoured barrel and full house loads it can be very nast to shoot, I never enjoyed it and am glad to sell it.
 
Some barrels are just strange,in a 24" or 26" barrel a 300wby should outpace the win without a problem.In the 4 or 5 wby I've had it's never been a problem to add 100-150fps over the win.It is a long range killer with very few peers.

The bullet was a 180gr tsx launched out of my 300ultramag at 3380fps.I have verified the velocity over two chronographs.The shot distance was just under 200 yards with a resulting impact velocity in excess of 2900fps.You will notice that no petals broke off,despite the fact that the bullet destroyed an entire section of an elks spine.This is an actual hunting result ,not a simulation using some other material.

I have to call BS on this one. How does a bullet travelling 3380 fps with an impact velocity of over 2900fps not completely pass through the animal, oh yeah, cause it hit the spine...but didn't lose any petals after expanding through that much bone.

Let me guess, the bullet retained 110% of its weight(it actually gained weight) and you found it afterwards 10" deep inside a poplar behind the elk:rolleyes:.Whatever. You must hunt with my brother.
 
See what you've done Bartell? Is there anyone who has some hard data regarding their .300 Wby loads with 200 and 220gr bullets?
For comparison:
.300 WM, 220gr Partition, H1000, F215M Primers W-W brass, 24" barrel - 2858fps
.300 WM, 200gr Partition, H4831, F215 primers, PMC brass, Tikka 695 - 2946 fps

The second load is my friend's, I don't know how long the barrel is.

My 300 Win mag gets just a tad over 3000 fps with 200 gr Barnes X bullets using Norma 204 powder and Rem 9 1/2 mag primers.

Load the same for my friend in his 300 Win, So far, two moose, two bison, never recovered a bullet. :D

Mod. 70 Win. push feed 24" barrel H4831 3100 Fps. 200 partition. Several 300 WBYs 180 grs IMR 7828 3300 fps with good case life. It's 100-150 fps faster than the Win. not much real world difference but your head knows its there.

And I can tell you sir that the 300 weatherby must be one dandy cartridge cause you've just created 12 pages of bickering about it - and for it - all ready :D

yes! because deer and moose most people are using their fast .30 cals on can really tell the diff between a .30-06 - 300mag - 300wby inside 200yrds :rolleyes:
