Sorry haven't ... but Hodgdon data shows a bunch for those ...seems Ramshot Hunter bumps along about 3600 fps(depends on barrel length)...
Load 80 grain ....RL17, IMR 4350 , Hunter ....and all those about this burn rate range would work well ...
Every rifle is different.... so you gonna need just work up a load that works in your rifle...

the newest Hornady manual suggests that several powders performed well, especially V N140, IMR4064 and V N160 and those ran that bullet as high as 3300 fps. The highest velocities came from IMR4831, H4350 and W760 at 3400 fps with that bullet.
Their test rifle was a Winchester 70 with a 24" barrel

These are software generated loads that may be over pressure in Your rifle ... and are for information only ...you must work up the loads by starting 10% below and working upwards ...
