7saum with 197 SMKs in 700LA. Experiences with WC872 or AA8700?

[slm9s]

I have a lot of the surplus powders AA8700 and WC872. I use them in the 50bmg but in smaller cases such as 6.5x55 (tho it has lower velocity). Anyone have any experience with the 7saum and heavy bullets?

872 could be too slow and give lower velocities or be bordering on low pressure. I used WC857 in 7mm RemMag with success.
