I purchased a bunch of WC852 from GIbrass and ran tests on it.

Understand there are a number of different burning lots of WC852. Accurate Arms bought one lot, sold it as 2700. I am certain current AA2700 is newly made but you can look at the data for 2700 for guidance.

My lot of WC852 was too slow for any use in the 308. I could not get a decent velocity even with 190's.

I did find my lot of WC852 worked well in the 243, 6.5 X 55, 7.5 X 55, 30-06 and 270 Win.
