Ing, I don't know what MV you are getting with that... but on the Ruger I have, the ONLY powder that rifle seems to like is a charge of 40 grains of 3031...right up to the 175 grainers... got the load data off an older Hornady manual...

the Hornady manual also says that the MV should be in the 2400-2450 fps range... however chronographing mine.. with the bullet seated to magazine length... it says the MV is 200 fps faster than the manual says..

but since the brass ( Remington) never seems to show pressure signs at the primer pocket loosing any... and the accuracy is a tack driver... I don't worry about... I just use it..

get the same numbers and results out of the Model 70 Featherweight also..
