Help with SMP 735 powder

[MK20]

I have the chance to buy some SMP 735 powder in bulk which is rare for any powder right now. I have done a little research and it seems to be a bulk surplus 556 powder. Do you guys have any experience with or info on this stuff?
Thanks

I did a lot of testing with it in 223, Seems to be about 3-5% faster then H335. We used it at the shop, in 223 ammo. I have a shit ton of it, going to work it up in 308 here soon. good cheap blasting powder.

You ever get round to loading .308 with that SMP 735?

Nope. Never bought any.
