While I love the traditional vintage British hunting cartridges, to the point of waiting on time to stock-up a .318 Westley Richards barreled action in my gunsafe (and waiting on affordable loading dies!), I have said many times that imho the .338 Win Mag is the cartridge the British gun-trade was trying to 'invent' all along!

.333 Jeffery, .33 BSA, even the .318 WR all fall in line behind the .338 Win Mag when it comes to ballistics and performance down-range.
Hell, the oft-criticized belt was even invented by the Brits!

They almost did it with the .33 BSA. They just never loaded it with heavier bullets for some odd reason. It even has the belt and the bullet diameter is .338 inches!


.33 BSA
"The .33 BSA or .33 Belted Rimless Nitro Express, was developed by necking-down and shortening the .40 BSA. It was introduced in 1921 for the P-14 Enfield Sporting Rifle, catalogued as the BSA "High Power" rifle at the time. The projectile was only 165 gr over 60 gr cordite, and was a bit light for caliber which limited popularity in the hunting field. Factory loads were still listed by ICI up until 1955.
According to the dimensions in Fleming's book, the rim is very slightly rebated."
