I have scoured the forums for photos of the above cartridge but to no avail. Has Saeed ever posted a photo of this or the 375/416?

It's a 375/404 not 416. Iirc a slightly larger case than the 375 rum

Is that not (.375/.416 Rigby Improved) basically a .378 Weatherby?
4WD

I have made a 416 Rigby Improved.

Hunted with it in Zimbabwe.

Shot elephants, lions, buffalo and other plains game with it.

I also have a 375/416 Rigby sort of.

Talking to Mr Lazzeroni, I asked him to neck his 416 to 375.

He kindly agreed, and built me a rifle for it.

He did not have any 375 brass, so sent me 416 brass, and a 375/416 die.

Again, I used it on one safari in Africa.

Great velocity, I think I was hunting with 300 grain bullets going at 3140 fps.

Trouble was it did not have good penetration.

I did penetration tests here, and found about 2700-2800 fps with a mono hollow point bullet like the Barnes X and our own Walterhogs, penetrate most.

Being a curmudgeon I see no reason to "improve" a 416 Rigby. It shoots a 400g bullet at 2400 fps with pretty low (by todays standards) pressure. It should be enough, if it's not go with a 500 Jeffery or 505 Gibbs. Once again just my two cents from a cranky old guy lol.

Yes.

You sound like some who is happy to put up with a 60 year old mother!

Instead of her 20 year old daughter!
