WC860 Pull-Down powder and 50bmg AP load??

[Divernhunter]

OK....I was not able to get my prefered 5010 pull-down powder so I got WC860 powder to load 700gr AP bullets in for my 50bmg's. I had a paper with load data but misplaced it in the divorice. Can anyone give me some load data or a load they use with this poder and a 700gr AP bullet in the 50bmg??? I will be shooting it in an AR50 and a Viper bolt action rifles.
Thanks for any help

Isn't 860 rather fast for a 50? have heard of folks using 868 and 872, thought 860 was for the 06 based cases.

Ok, on edit I checked my chart, its just slower than AA-8700
here's the copy/paste from www.gibrass.com

Original application is U.S. .50 Cal. BMG ammo, used for the Ball
M33 and API M8 projectile. A ball powder which can be loaded using
Hodgdon H870 or AA8700 data. Just received a limited supply.
This is pulldown ball powder from Lake City.

The M2 ball rounds were loaded with 235gr of WC860.
Chamber pressure was listed at 55,000 PSI and velocity was listed as 2810, 78 feet fromt he muzzle.

This is just one of several loadings that used WC860.
