Any loads for 280 Ackley and 180 Begers?

[elmerdeer]

Hi guys I am getting my Win M70 280AI custum back from the gunsmith this week and would like to try the 180gr bergers. Has anyone found any good loads with this combo? My barrel is a Krieger FW contour with a 1-9.5 twist finished at 24", and the powders I have on hand are H4831,Rl-22, Rl-25, Imr7828,Retumbo, and Rl-17.
Thanks
Elmer

Thank you, I will work up slowly. What is your speed and can you give me some barrel specifics?
