I always have at least 3 lbs of Unique in store. It really is the most useful powder there is. One thing I like for beginners is that is fills the brass so getting a double load is very rare.
I use 4.5 grains and load everything because I bought much when I thought Hillery was going to be president.

However my most accurate load is 5 grains of P B. With a Montana Gold124 grain bullet.
