As stated above you will need HOT .44 mag loads.
IF you handload.Apparently, at the muzzle, the 200 gr. JHP does do better than the 240. It appears your energy requirement can be easily met.
Of course we could think outside the box and consider a Model 99 Savage. You'd have to find a used rifle, but they were manufactured in .300 Savage, which is more powerful than the .30-30, and .308 Winchester, which is more powerful still.
