W748 or W760 in 7.62x39?

I want to start handloading for my MAK90 due to some problems I've had with the steel cased ammo. I've been searching all morning for any data with these powders (I use these for .223 and .30-06) but haven't found anything.

Can anyone provide me with a starting point for these powders in this cartridge? I've looked at Winchester already and they have no load data for the 7.62x39 at all.

Thanks,

Allan

AA 1680
is the way to go

748 will be too slow

Thanks for the reply Zak - I was thinking the same thing after doing some more research through my manuals and online.

I was hoping to use something that I already have on the shelf, but I guess I'm not going to get away with it.

Thanks,

Allan
