This is not a discussion about rifles but rather... cartridges. I am having a hard time picking between the two. I see merits in both. I know most of you know that I am not a stranger to heavy kickers or reloading so we do not have to start at square one. One question I do have is if you can obtain the velo in the rigby that the 460 can reach? The 460 has an almost 1" free bore and generally a long barrel. Does anyone have experience with these two at 21'22 inches? I think Andy has a 450 that short. Anyone care too chime in on the pros-cons?

PS: Mike my new 378 @24" seemingly has no ends to the velocity I am getting.

.....Resonably priced ,,,,,,,not overly uncommon brass.. More arrordable ,which leads to more shooting which leads to better field accuracy......The 460 is my pick ,, But then the 450 Rigby /Dakota is no doubt a great round......For myself the benifits of the 460 outweigh the benifits of the 450.....And If I end up with a double in 450 3 1/4 ,,I won,t make a nomenclatural mistake at some point in time and end up somewhere with the wrong ammo..................................Plus it can provide brass for a 500 A-Sq. or 550 Magnum

I own a 460 on a very early (2 digit serial number) Bauska BBK action, McGowan barreled and reworked the action, George Hoenig did the stock. I really like it. I had it built about 20 or so years ago, before the 450 Rigby was in existence. I load mine with 500 gr. bullets between 2200 and 2300 fps. Low pressure, very accurate, brass lasts a long time. The other advantage is that 460 dies are reasonably priced as is the brass. Just my $.03

Just imagine the hassles of a belt VS non-belted case.
Just imagine the fun of setting the FL die with that goofy shoulder the Wbee has.
Just imagine a simple way to get the 450 Rigby/Dakota...buy a CZ in 416 Rigby and either bore that barrel or buy a new one.
Just imagine calling Jamison and ordering a couple hundred Rigby cylindrical and FL sizing them and going load testing.

Just Imagine...

The 450 Rigby is almost impossible to find ammo for and brass goes for about 80 bucks/20. The 460 Weatherby's been around for a long time and it's here to stay. With proper bullets nothng comes close when it comes to penetration.

Brass is readily available and costs half as much. The 460 easily bests the 450s (Rigby or Dakota) by about 200 fps plus if that's your choice. The Rigby's lack of a belt allows for greater magazine capacity, but you can work around that by ordering a bigger magazine for the 460.

I've been loading Weatherby brass and calibers all my life with no problems. I guess I'm a genius. What caliber did I order for my custom Big Bore?: 450 Dakota. jorge

Buy 416 Rigby Brass and FL with the 450 Rigby Die.. There's a lot of Brass.. Now, Headstamped Brass that's another question.. This will happen soon also.. Karl S. anything to add..

IS:
#1...No hassles as of yet, either with my 460, 458, 3 different 375 H&H's, or my 338.....

#2 What hassle? Read instructions, works fine!

If your going to that much trouble you might as well build a 470 Mbogo. Larger case capacity, less pressure at any comparable velocity, larger bullet surface area. If you reload it's not a problem.
Take good care which ever choice you make,

Yes! Not to mention scoring very high in the "cool" category.





Compared to the 460WBY or 450RBY, its all that AND a bag of chips.

Not that I am biased or anything.

a belted case, by its very configuration, cannot be as easy to set up one's dies for as a non-belted.
Roy Wbee finally came clean and admitted he did that dorky shoulder to make it difficult for other gunsmiths to cut reamers. IIRC after the 300/375H&H came out, there were not many other british rifle builders doing belts. It was a fad, like burning your bra...

460!

Because you know you might want to load it to full house and knock down a semi!

I have two 460 weatherbys, one is a mark 5 and the other is a WDG model. I have never had a minutes problem with either. For the last 6 or 7 years, the factory load for the 500 grain bullet has been taken down to 2600 ft/sec instead of the old 2700 ft/sec loading. Means less pressure on really hot days. I would go with the 460 Weatherby.

If you don't handload and want usable power: 460 Wby.

If you hand load and want greater usable power than the 460 Wby: 470 Mbogo

Compared to 460 Wby, the 470 Mbogo has greater case capacity and greater bullet diameter, so whatever MV or KE the 460 Wby can do, the 470 Mbogo can do more at the same or lesser pressure. 500-grainer at 2700 fps for the 470 Mbogo would be a lower pressure load than for the 460 Wby, that is for sure.

I have loaded the 470 Mbogo with 500-grainer at 2685 fps on a warm day with no pressure signs.

With both using 500 grain bullets, the 460 Wby will have a greater SD, but this may be a disadvantage, especially with the monometals these velocities deserve: longer bullet = less stability in some situations.

The .475/500-grainer is still well over .3, and more than enough bullet for anything. More SD is not always good.

To Gerard Schultz:

I have owned two 460s with the older Pendleton Dekicker and also chronographed two others with the Pendleton.

The Pendleton Dekicker opens to a large chamber full of little holes and then comes back, from memory, to about .475.

My guess is that the Mark V 460s with the 26 inch barrel and the Pendleton probably has a barrel that equates to about 23 inchs.

115 grains of IMR 4350 and a 500 grain Hornady does right on 2500 f/s in them and they are Oehler velocities, not Chrony That is quite a few grains under what you can use.

The rest, what RIP said.
