What is the difference between the .700 ne and the .700/577 in terms of case size and ballistics?

The second is the first necked down, giving roughly the same capasity under the bullet. While the first will knock your feet of the ground, the second will also untie your shoes.

Neither are usefull hunting weapons, both would be fun on the range.

700/577 ...
Okay, ,I am amazed.. the 577 nitro, either 3 or 3.25 inch, has no trouble in generating enough recoil to make most shooters, including me, decide 4 to 10 rounds is more than enough!!!

the woodleigh .585 750gr bullets are designed with a MAX impact of 2100fps. The 577 NITRO 3" can hit this, at teh muzzle, with no problem.

the RECOIL and usability of the 577 3", in a 14# rifle, is amazing.

Next - 700NE cases are what, $35 each? And then you have to build on a jumbo action, and I mean HUGE!!! action.

Let's say that you could get 2400FPS with this beast with a 750gr. That's 577 trex stuff, and if you see Saeed's videos, that's not a managable recoil level. that would mean your rifle, in order to be shootable, would need to be in the 18-20# class.

yea... good fun...

700 NE - 1000 grain seventy caliber bullet at 2000 fps.

700/577 NE - 750 grain fifty-eight caliber bullet at 2400 fps.

Westley richards claims .700/577 900 grs at 2300f/s. Energy 10280 ft/lbs, compared to the 8900 ft/lbs of the .700NE and 7600 ft/lbs of the 600 NE.

I still think it would untie your shoes.

Both that and the .500 Rafiki seem like they would belt the snot out of you (especially the .700/.577 and have to be built on a .700 size action and barrle brrech width.

Does anyone know of any .500 Rafikis that have been built and /or used on a hunt? Has anyone here seen one or shot one?

Cheers

I've no experience with the .700NE due to ignition problems and cost of components. Hoewever,The .700 RLG is built on a .50BMG case/ Mcmillan action. It easily launched 1000gr bullets over 3200fps. Even in a 24lb gun, Recoil was stout!-Rob

The 500 Rafiki is most interesting, and I will be waiting for any answers to your question.

WR specs for the 500 Rafiki:
570 grain bullet
2420 fps MV
7500 ft-lbs KE

Those would be my favored specs for a modest 500 A2 load, with the GSC FN solid, and that makes it satisfactory for Portuguese-Texan Heart Shots on elephant.

I forgot that I posted this to a similar query in Nov 2003:

Petersen's _Rifle Shooter_ magazine, June 1999, article by Terry Wieland, "Last Page" page 90, gave some details and opinions/gossip on the cartridge. Terry said that Westley Richards:

"... necked the ludicrous 700 NE down to '.500 caliber,' meaning .510" bullet diameter, and lengthened the case to 3.75" from 3.5". Instead of calling it the '700/500 NE,' WR chose to call it the '.500 Rafiki.' 'Rafiki' means 'friend' in Swahili.

"Gossip: WR started test firing it and found the pressures were far too high for a double rifle to take ... By the time they'd backed it off to acceptable levels, the velocity they got with the 570 grain bullet was very little different than the standard 500 NE (570-grain bullet, 2150 fps, 5850 ft.lbs.

"Not being the type to give up, WR is working on a variation ... a .700/.577."



It seems to be a lot of pie in the sky.

The 700/577 NE would almost equal the 577 Tyrannosaur if a double rifle could handle the pressure.

The .500 Rafiki could almost equal a 500 A2 or 500/470 Mbogo, or 500 Jeffery, IF a double rifle could handle the pressure.

Once again, bolt action trash comes out on top in the comparison.

Now let us search for WR double rifles in 500 Rafiki and 700/577 NE.

I see that Horneber makes brass for the .500 Rafiki and .700/.577 NE.

Who makes double rifles for them? WR?

That must be a light load for wimpy guys.

WR makes the rifles. Probably only made one of each.

Horneber makes the brass, Wolfgang Romney loads the ammo using Horneber's brass, and Westley Richards sells the Romney ammo under their brand name with a "W-R" headstamp.

Only one of each? A shop mule for each?

Supposedly a gentleman on the Arabian peninsula who needed something to show his friends.

Oh? I see. An outside bankroll for the WR and Horneber stunt. And it lives on in obscurity for posterity.

Charlie Kokesh could use some of that action. Maybe a rhino-elephant combo hunt to promote something new.

i loved my 700 nitro and if it wernt for the fact i wanted to buy a house asap i would have kept it.

the 700 nitro is not that bad and a 15-20 round range session was quite fine

in prep for my elephant hunt i was shooting 20 rounds of 700 and 20 rounds of 500 nitro every sunday within maybe a hour and half.


i will probably buy another 700 nitro but put it into a farquson action for buffalo hunting

my new elephant rifles are 505 gibbs 600 grain bullet at 2500fps and propably another 500 nitro double havnty desided.

John Taylor claimed the .600 NE to be way to heavy to carry in the hunt. Since the 700 is heavyer still, does it come with a sherpa, or are you just that big of a brute?

There was an article in African Hunter some years back about carrying a .700 NE double on an elephant hunt. I think it was called "The .700 Syndrome" or something like that. They carried the rifle by a team approach and each member of the team suffered the .700 syndrome - EXHAUSTION.

Famous elephant hunters like Feldstein and Eder must havee lots of Gunbearers on ther Track

Seloushunters

this .700/.577 seems pretty interesting, and I'm doing some searching around on the net right now. But, maybe someone can give me a ballpark in this forum.

Question 1) is this caliber only available in bolt action or can i get it in both bolt action and double rifle?

Question 2) approx how much are we looking at, and how long would it take to have to have it manufactured? I'm expecting big numbers, and thats fine, i just want to know how much this is going to cost me?

NIck,
you could PROBABLY build one on a mac-bro's bolt action. iirc Saeed's 700 is that. Rob posted on his 700 BMG, and I think that what you are looking for, if you wanted this, is a shortened BMG, necked to 585.

then again, this performance "level" is that of the 577 Trex, which i believe you can have built for about 6500.

or even the 600 overkill, for about 4500, including dies.

On a double gun, I would expect, if you choose searcy, you would be looking at the same price, or more, than a 700 NE... I believe that starts at 35k.

brass is nearly $40 PER
reloading dies would be about 250, and 3 months
reamer, about the same
I would expect, if you wanted a double gun in this, you are probably looking at 1.5 to 2 years.

if you wanted a 577 trex, probably less than 6 months

same for 600 overkill, http://www.hunting-rifles.com/S550DGR.htm

I am sure Peter Hambrusch can build one for you for about $50K, as he does bolt guns in .700 NE.
