The powder can often be identified by measuring a grain.
The problem is that bulk powder speed is precise but not accurate
So with bulk powder I find some powder in the Quickload library that matches. i.e. I got 32 pounds of surplus pull down IMR4895 from High Tech Ammo, but it did not behave like canister IMR4895.
But the speed [velocity over chronograph and threshold of brass deformation] and density matched H322, so I can use it without any more work.

Personally, its not worth the risk and hassle transferring powder from 30-06 surplus to 308. I guess you could extrapolate the 308 load based on the average weight found in your pull downs. For the pennies a round powder costs seems like a hassle.
I think when I pulled down some Korean 30-06 (forget the date) the powder was ball not stick. I've seen both ball and stick in Greek. I've also seen same date stamp on USGI with very different looking stick powders (4064 versus 4831 looking stuff). So even if you are pulling down tons of ammo from one supplier or date code, beware the powder type could vary and things could go "boom."

If it came to about 4lbs or more it would be worth my while to work up a new load maybe even 2lbs but less then that by the time you work it up it would all be gone so not productive. I sometimes use rifle pulldown powder in pistol if it is fast enough & less would be more worth while but it is rear to find such a treasure.
You would be best to just shoot it as is or take the average & rebuild them in small amounts.

There's a strong chance that Korean ammo is berdan primed, so in addition to the primer, you'd also be needing new brass to go along with it.
Me personally, I'd just shoot it, unless there's a safety concern with the ammo itself. Corrosive primers are not a problem, just so long as you clean your gun afterward.

Korean 30.06 ammo was built on U.S. machinery. The powder is a bulk version of IMR4895. Unfortunately, a good bit of the korean ammo was poorly manufactured from an assembly standpoint, but the components are all good stuff.
Your idea of pulling it and reloading it is a good idea. The idea of using the components after weighing the charges to get an average charge weight is a good idea. Reloading it back in the original cases is a good idea. Re-using all the components is a good idea.
Once correctly assembled, it should shoot as well as any other GI surplus.

Are you sure the primers are corrosive? I have shot a lot of Greek ammo and none were made with corrosive primers. Might this be the ammo that's currently available on the CMP site? If it is the primer are not corrosive. Also, even if the primers are corrosive what's the big deal? Clean your rifle when you get done shooting and get home and you will not do any damage at all.

Regarding Korean ammo. Both the "KA" headstamped ammo and "PS" headstamped ammo are boxer primed. However, the "KA" ammo uses corrosive primers. Here's how I remember it: KA = Korrosive Ammo; PS = Perfectly Safe.

Thanks Don, I didn't know that...

That's funny; I use the same little reminder!
I shot up all my KS stuff back in the 90's, but I have a few thousand rounds of PS loaded in en-blocs for the M1.
