bronko does just about what I do.
Normally I don't go for speed as much as accuracy. Speed is nice,accuracy better. If it works out to get both thats great.
I like to wipe out the barrel after about 20 rounds or when changing powders.
I find that slow fire keeping the barrel from getting hot is better.
As the cost of components is so much more now I do quite a bit of research on loads.
If competitors are shooting the same load and doing good with it then usually something close to that will work for me if starting with a new caliber.
