WC872 in 257 Wby & 338 RUM

[tucker05]

Anyone out there have any experience with WC872 in the .257 Wby using 75, 87, 100, 117 or 120 grn bullets?
How about the .338 RUM using Sierra SBT in 250 grn?
I have the opportunity to purchase a rather large quantity of this powder and am looking for any feedback with respect to the above. I realize it is similar to H870 and AA8700 but I am looking for actual user data with the following in mind:

load weights
accuracy
velocity

Feel free to PM me if you are uncomfortable posting load weights

Thanks in advance

What are you paying for it? I know a guy with 8lbs but he wants $20lb for it. WayToo much. Thought I would use it in my 7mmSTW and 338LAI.
