Is there someone who knows the dimensional differences (neck length, shoulder diameter, shoulder angle) between these chamberings?

Thanks

From:

http://municion.org/
(click on "Fuego Central/CF" in upper left corner of Home page to find cartridges.)

.510 Wells Express:



.500 A-Square:



The photos below are not on same scale.
Base to shoulder length and shoulder diameter are greater on the the 500 A-Square.
The neck is longer on the .510 Wells.

.510 Wells Express:

.500 A-Square:


.510 Wells: 30-degree shoulder angle
.500 A-Square: 35-degree shoulder angle

The 500 Mbogo and many other cartridges can be found there also.
500 Mbogo:



500 Mbogo shoulder angle is 35 degrees.
I never noticed before that the municion.org drawing has a wrong COL for the 500 Mbogo 3-Inch cartridge.
They have shown 90.20 mm (3.551") for COL of 500 Mbogo.
It should be 95.25 mm (3.750").
I should know.
Maybe a typo of 95.2 into 90.2?
A CZ 550 Magnum magazine box is over 3.800" long inside.

Thanks for your info, but how did I know 99.99% if anyone will have it it will be you.

Thanks again

I've always thought that the .510 Wells is just .460Wea case necked up without any other changes.

However this drawing (measurements) look to me like if the entire case body was swadged.

I like and prefer the .510 Wells longer neck and the shallower shoulder angle.

And the 500 Mbogo is similar to a 500 A-Square without the belt, same 35-degree shoulder, just a gnat's eyelash bigger in diameter and further from base,
but with a longer neck, neck slightly longer than that of the .510 Wells.
Once upon a time I had a 500 A-Square imitation made with a 30-degree shoulder instead of 35.
Called it the ".510 JAB," short for ".510/460 Weatherby Improved Jenkins And Berry."
Now I prefer the 20-degree shoulder, even on a shoulder as skimpy as that of the "500 Bateleur," a work in progress.
