I shoot a Ruger Redhawk in 41 Mag.. I don't reload anymore but I can give you a recommendation of factory loads. I use CorBon 250gr HC loads for hunting. On paper they have the same ME as a 44 Mag 240 factory load, but with a little less kick. For practice I shoot Remington 210 SWC ammo. It is pleasant to shoot. Good luck!
