Don't sweat the "hotter" loads bit, you'll get up to 300 fps (depending on the powder) over revolver data when using the same load in a rifle.
You could always order the double cavity mould from Tom , 1 cavity plain base and the other the copper diaper .
The only trouble I've ever had with swc bullets in a levergun is trying to seat them to far out the nose will hang on the end of the magazine tube and eventually will cause the lifter to break. But seated normally there's no reason why a swc bullet won't work in a properly built and functioning levergun.
