Great Q. I plan to mostly use for range time, both paper and steel. I like the way the heavier bullets shoot compared to the 115 gr. My main focus will be on precision and not so much on velocities. I really just wanted to get a powder choice or two to start with to see what I learn I like and don't like with the loads it can produce.What do you want to do with the load?
If you are going to shoot action pistol where heavy bullets and fast powders rule, you want AA2, Bullseye, or other fast powder.
If you are thinking that you want to load for self-defense, and you think 147gn is the right weight, you would want a slow powder for maximum velocity.
The thing is, you have to know what you want before you can make a decision: maximum velocity, minimum felt recoil, what?
