Alliant Bullseye is one of the most versatile powders for pistol, especially for moderate loads. It meters very well and isn't temperature sensitive. IMHO, people who worry about the volume of the powder being a safety issue (double-charging) are focusing on something to save them from issues, when they just need to be alert and focused during the reloading process. When you get tired or bored, you need to take a break or quit for the day. Choosing a powder can also depend on what kind of bullet you are going to load, i.e. jacketed, plated or lead. I load some of my 115 gr. FMJ 9mm bullets using Power Pistol, but that is when I want to load to high velocity.How about Bullseye?
I have a pound of that I bought a while ago and I'm in a very similar situation as the OP. Same press too.
