.404 Error code Jeffrey
In 1905, London based gunmaker W.J. Jeffery & Co developed a cartridge to replicate the performance of the .450 Nitro Express. Jeffrey wasn't reinventing the wheel. He refined it.

The .450 Nitro Express (NE) is a beast of a cartridge, and there was nothing inherently wrong with it. It thumped like a wildebeest, and it'd drop an elephant six times the size. However, the .450NE was chambered in single-shot rifles and single-shot rifles only. Better make that shot count...

Now that's where our man comes in. Jeffrey developed a cartridge that duplicated the performance of the .450NE, but it was built for bolt actions.

A 300gr pill stacked on top of enough powder to make Pablo Escobar cry......

Enter the .404 Jeffrey

Belting out of the barrel at 2,600 ft/s and swinging Thor's hammer with 4,500 foot-pounds of force. Wow.

The cartridge gifted hunters manageable recoil and dared them to find something it couldn't drop. And if you did? Well...

Jeffrey also designed her to sling 400gr missiles coming out of the chute at 2500 ft/s and delivering 5000 foot-pounds of pure carnage.

Holy. Shit.

By today's standards, that's impressive. What's truly incredible is that this was 1905. Subsequently, the .404 Jeffrey dominated the South African Safari scene and became the King of the African Sahara for the next 45 years.

Due to the fading ammunition industry of the British Empire, the cartridge was becoming obsolete as it surpassed 1955.
Winchester stormed the market in 1956 with the legendary Model 70, chambered in .458Win Mag.

Whilst not ballistically superior to the .404 Jeffrey, the US industrial complex produced "big game" firearms and ammunition at an affordable price. Granting those wishing to go on Safari an option without mortgaging the house.

"Yeah, it's not a Jeffrey, but the .458 kept my wife from leaving me for one."

Long story short, you found this page due to a 404 error. A 404 error is the website telling you that whatever you were looking for doesn't exist. But nobody likes returning home from a hunt empty-handed, so at least you met .404 Jeffrey along the way.
