500 Pirro

[de Forrest]

ANY ONE OUT THERE HEARD OF A 500 PIRRO...BUILT ON A 460 WEATHERBY CASE,VERY SIMILAR IF NOT IDENTICAL TO A 510 WELLS EXPRESS.

 

[Wyatt Smith]

So is it similar to a 500 A square?

 

[IvW]

Why would anybody want to know that? or be interested in such a creation?

 

[WAB]

Apologies to anyone who has one, but it sounds awful!

 

[de Forrest]

I dont get it,are you big game hunters ,shy in shooting a 510, 750g cartridge.

 

[WAB]

I’m thinking of it in terms of the excess velocity and this recoil of a .460 Weatherby. My Lott shoots a 500 gr bullet at 2,300 fps. It is very manageable and is decisive on big game. The .460 fires that same bullet at 2,600 fps, producing punishing recoil for velocity that is unnecessary at big game ranges and potentially detrimental in terminal performance. As you step beyond the .45 caliber, 500 gr projectile into larger calibers, the proven performers are hurling their slug down range at 2,100 to 2,200 fps. So to me, the 500 Pirro does not sound appealing or practical at all.

Nobody is afraid of such cartridges , but the 500 Jeffery in a bolt action rifle and the 577NE in a DR are at the limit of what is useful , and that really only for elephant hunting.

Nobody needed a cartridge 600NE 100 years ago and that's why i don't know the reasons for developing such cartridges nowadays.

No I don't think anybody is shy here. Most have common sense, have a very good idea what works and what does not on African DG. A 500 Pirro I suspect is not one of them.

Last time I shot one of those it was mounted on the front of a Casper and was fed with a belt, the last call on the radio was "Contact, contact, wait out...."

Perhaps you could share with us exactly what this is?

I have read about the .500 A Square , Master Smith. It apparently uses a 600 grain bullet. However , no one here appears to own 1. It has always intrigued me. Is it any good ?

No one here needs to prove themselves shooting anything they don't want to.
Trying to goad members this way is not conductive to getting the results you desire.
Ask polite questions in a respectful manner and you in turn will receive respect along with answers.

It would be my first choice for hunting a Tyrannosaurus rex or woolly mammoth, but for big game today I would say it’s a bit too much.

With these 510,all I need is 1 shot.

I support your philosophy . But with a good .375 Holland & Holland magnum , appropriate bullets and proper shot placement , you can secure even the largest bull elephant with a single shot .
An overtly aggressive recoiling weapon will only worsen your shot placement . Mind you , a ".500 Pirro "( whatever that is ) to the stomach will not kill your quarry anymore than a 9.3 × 62 Mauser to the same region will.
Look , you appear to be a beginner to the world of big game hunting ( which is perfectly alright , as we were all beginners once ) . Why don't you tell us what quarry you are after , so that we can point you in the right direction ?
For most of my beginning clients , l would recommend the .375 Holland & Holland magnum ( l personally like the pre 64 Winchester Model 70 , but any good design will do ) . If you would like to go higher , maybe a .404 Jeffery ?
While l have no first hand experience with the .404 Jeffery , l do have experience with the .450 / 400 Nitro Express ( which is the double barreled rifle equivalent of the .404 Jeffery )
It should be more than adequate for whatever you are going after .
But an obscure wild cat cartridge using a 750 grain bullet and the recoil of a .460 Weatherby magnum is definitely not the way to go , based on my experience.
For hunting anything , the golden rule is that your rifle must allow you appropriate shot placement at all times.

You always have to shoot well because no matter how big the caliber , an good shot placement is very important too. Nothing go down after a simple energetic touch.

I am turning 63 this yr. Started hunting in 1972 so I have covered some ground.What I have uses were / are 375.375imp, 45/70, 348/450, 577/450, 458,458 lott,416 rigby,416 rem,338 lapua, 470 nitro, 500 Jeffery. 505 gibbs, 300 weatherby, 510 wells express, 500 pirro.No one seems to have heard of this wildcat...what I am looking to find out is, what came first 510 wells or the 500 piero. Both the dies and barrel are stamped 500 Pirro.

 

[de Forrest]

I forgot to include my 577 nitro.

 

[de Forrest]

And a 460 weatherby..

 

[Certus]

You guys confused me by assuming a .460 necked up to .510 will be run at ridiculous velocities. No, the .510 wells isn’t run any hotter than the above praised 500 Jeffery. They have a similar case capacity if I recall.

Most people who shoot a .510 wells down here run 570gr .500 Nitro bullets at moderate velocity.

So there is a reason for the cartridge - think of it as a .500 Jeffery with more common brass, a cheaper build and less feeding crap to worry about. Seems good to me (I used to have a .416 Rigby necked up to .510).


De Forrest - there’s about 30 million versions of a .460 necked up to .510 lol. I may be exaggerating but there’s at least 3. .510 wells, .500 Pirro, and, what I think is the best named one, .500 weatherby (which weatherby should adopt as their own).

 

[de Forrest]

Sure there are.but who was first .

 

[Forrest Halley]

I forgot to include my hot air balloon, but I couldn't see what it added to this discussion.

In truth, I'd like to see a picture of the round in question and the rifle too. My googliness is not sufficient to produce a visual aid.
