Imagine how bad your reputation must have been that no matter who messes up, it's only you getting cursed
Those were not OFB ammo
He clearly mentioned a name "Shaktimaan"
There's an Arms & Ammunition manufacturing company in Bellary, Karnataka by the name "Dwarka Arms Stores" who uses this brand "Shaktiman" on both the 12 gauge ammo and SBBL/DBBL guns the make. A bit of a backstory about them from a news article
"He got into the arms business in the late '60s by converting old guns discarded by the police into usable ones. After he became a partner in Sujatha Arms Factory in neighbouring Guntakal which had a licence to convert 525 arms annually. By 1977 he established Dwarka Arms and merged it with Sujatha and obtained a licence to manufacture 700 breech and muzzle-loading guns a year. Soon he got licences to manufacture three lakh blank cartridges, 3.75 lakh live cartridges and one lakh lead shots. They now manufacture an estimated 60,000 guns every year."
Now as usual, some technical blabbering from me. Making shot-shells is way more easier than making a rifle cartridge. In mechanics we use a terms called "critical dimension", meaning a dimension that if not kept accurate can hinder the proper functioning of a machine. In case of a rifle cartridge pretty much everything is critical; base diameter, shoulder diameter, length, neck diameter, headspace...a diameter of 6.91mm becomes 7mm and you won't be able to chamber a round. Not to mention the extreme pressure at which these operate, around 400MPa. Shotgun shells are much more forgiving as you've just three four critical dimensions and the pressure is way lower at around just 80 or so MPa...so much so that even paper is sufficient to make most part of the case. Thing are made even more easier by the fact that in rifle you'd need to make a bullet with complex geometries made by merging multiple cylinder, tangents and secants then a core of lead with a jacket of copper and everything needs to be in tolerance of 0.1mm otherwise you'd blow your barrel. But in shot-shells you just need a lead sphere of diameter 5mm...that's it.
So because of these there are multiple small scale shot shells manufacturers here in India. And obviously you can't expect Remington or Winchester level quality control from them.
By the way, another interesting or kind of funny fact. In 2013 this Dwarka Arms was raided in connection with making arms and ammunition for selling them to illegal markets. So ya, that's there too
