iirc it was Remington that even had a special 410 only primer, it was quite a low brisance primer.
I can't dredge up the specifics from the back of my head on why they even made it, but it was available to the public for a few years.
to make things even more fun.
Winchester used to make different primers for other countries, Australia in particular used to get some odd ball stuff like they wanted to test a market somewhere before doing the final packaging for America's consumers.
they'd get stuff like the AA compression formed hull disguised with high brass heads, a few different brisance primers with varying load data for each one, and all sorts of stuff like that.
that was before they flipped and was having other companies [Nobelsport] make their primers for them to use in their low dollar promo loads. [send them a specification and they send you a product]
those companies [nobelsport] of course dumped their extra's on the market along with their normal primer.
making things even more confusing for the consumer because you now had a low brisance primer with almost the same number as the normal primer from company A, but with the same measurements as the Winchester primers on the market ''only they looked just like the ones you got in your promo winchester shells''
don't even get me started on the Federal hulls that took Rio's over sized primers because the hulls were made by Rio.
only they were cleverly disguised as federal stuff by having the federal name all over them, only nothing federal made fit or stayed in the hull.
