Marrakai - Oh dear, here we go again - more 'tit for tat'!

Perhaps I'm naive, but I tend to think Rigby's contemporary views can be accorded some weight!

Please understand, I don't discount the 'bottle shape theory'; I would just like to see some some documentary evidence that it was part of the 'other conditions', or that it was the only condition to be met to qualify as a 'magnum'.

If the latter, the term could be applied to literally thousands of cartridge designs. How does '.255 Jeffery Rook Magnum' sound?

On the other hand, there being a high level of classical scholarship around back then, perhaps somebody balked at the prospect of calling a cartridge something like 500/450 'Big' Express and resorted to their Latin dictionary for a more catchy word and came up with 'magnum'?

Afterall, it was just a longer version of the 500/450 No.1 Express, which also happened to be a bottle-neck. I wonder why they didn't apply the term to that?

Well, I guess all this is just conjecture, and without hard evidence, or a time capsule to go back in time to check it out, we will just have to agree to disagree!

The other members will just have to make up their own minds?
