I'm the same way, when I shoot my .44 its with full powered loads. When I want light loads I shoot .38s in my .357. I have a few .44 Spl cases, but they are in no danger of getting worn out. If the .44 was my only handgun, I would make a point of loading light loads in .44 Special cases so that there would be no chance of mistaking the light loads with the heavy ones, particularly if I used the same bullet for both, as I do with my .38/.357 loads. Expecting a 250 gr slug to pop out at 700 fps and getting 1400 would be quite an eye opener.
