yugo 198 grain belted corosive ammosilly question i should know the answer to by now

[the old gringo]

ok gents be nice here.
. i have a lifetime of ammo for my k98's to use if it is ok. i have some nice 70 vintage yugo belted brass case 198 grn. corosive machine gun ammo.i know the berdan primers are corosive but is the powder ?????
i would like to pull bullets and use powder and bullet in a brass reloadable case with non corosive primer.
my mausers are family bring backs which are in great shape. i would like to keep them so. but hate there are no mil spec loads around for these rifles. i would like to hunt with them , and not with the pityful down loads all us data is not half of the rifles original load. i am aware of the older .318 bores but damn how is the herd of man to be culled anyway??? thanks

Why not shoot the ammo as is? Just start your cleaning wit hwater or a water based cleaner (like soap) to flush out the salts. Easy and cheap. Whether the powder was sufficiently washed to remove the acid before loading in the seventies is an unknown, but if there's internal corrosion then there's a big clue. Usually Yugoslavian ammo is OK in that regard.

Seems like a boatload of work just to avoid cleaning the rifle...

The primer is what is corrosive not the powder. The only time I have seen any problems with powder is when you have a single base gun propellant and the stabilizer is depleted. You will get a Redox reaction that will turn the propellant red.
Any red powder, red rust like coating, red gas, or if the powder has become tar like is grounds for disposal of that propellant.
The gas by the way is highly poisonous and should not be inhaled.

Do not keep any old powder if it has any of the above characteristics. The easiest way to dispose of it is to spread it on your lawn. It will make great fertilizer.

As far as reusing old propellant, I would just go purchase new and be safe, not sorry.

Take a bottle of windex to the range with you and use it with a patch every 30 or 40 rounds and again when you get home and if you have any black powder solvent use that as well.
