Having had dismal performance and extreme dirtying of two guns to the point of failure to function after three magazines or cylinderfuls, I now avoid Unique like the plague. The flowers liked the nitrogen boost......
I would advise a new reloader to use ONE powder, and work on technique, and try different loads/bullets. Try another powder once you have more experience under your belt.
My initial pistol loading was Red Dot. Worked well for a couple years. Now my 'go to' powder is Bullseye.
