Hi all
In August 1899 the Government of India prohibited gun dealers from importing .303, .577/.450 MH & .577 Snider riflers and ammunition, to deny dissidents from obtaining said items. Indian residents with authority to possess firearms, i.e. Europeans basically, were exempt from this ban and continued to import/export freely.
In February 1901 the Government of India completely banned the importation of .303 calibre rifles and Martini-Henry rifles in .577/.450 calibre and .577 Sniders. (there were obvious loopholes in the law here as observed by ‘The Field’ newspaper in 1901. Legally you could import into India a double rifle in .577/.450 calibre.) Under the new provisions of 1901, Indian residents in possession of the banned firearms could obtain a licence to buy up to 200 rounds per year and selected European and a few Indian gun dealers were licenced to stock up to 25,000 rounds of ‘banned’ ammunition for sale to licence holders.
How far did this affect import of firearms and ammunition into India? To some degree - because customs officials and others could not discern and difference between .450 and .577/.450 - but how many sportsmen would be using the obsolete .577 Snider and .577/.450MH by 1901??? Not many. Mostly I suspect the India ban was a useful marketing ploy for British gun and ammunition makers. H&H’s .465 ‘India’ cartridge was introduced 6 years after the ban - and its ‘Velopex’ bullet was amore important development than its calibre.
Sorry don’t have anything in Sudan.
Doc - can you date that 8mm x 50R LE from the Proof marks - I suspect 1919 onwards - but would be interesting to know.
