Since you are new to reloading I would go with Unique. As stated previously in most loads it will fill the case over half full so you're less likely to double charge and it's rather forgiving if there's a slight under or over charge. It's a good versatile powder. I use it to make plinking loads in .380, 9mm, 38 spec, 357 mag and .40. and find it plenty accurate. Once you get comfortable with reloading, then is the time to try different powders for more specific applications.
