Reduced .22 Hornet Loads?

[dovehunter]

I have been considering using reduced loads with maybe 40-45 gr. cast round nose bullets in a .22 Hornet for squirrel hunting. I have checked around a bit and haven't been able to find much info about the best powders to use and charge weights. I would think that Unique may be a good powder for such loads. Can any of you give me any recommendations or is this is a totally dumb idea that I should just drop?
