Scott, I use mainly factory for club matches, whatever is on sale when I am getting low.
Reloaded ammo is Zero JHP 147's with Tite-Group or Universal Clays most of the time. SR4756 is also a good choice, 231 will do a good job too if that is what you have on hand. Honestly, I have never worked very hard on 9mm ammo. I use whatever I have on hand instead of trying to find the best load and I usually have at least 8 pounds each of Tite-Group, Universal, Unique, Bullseye, Clays, etc.
With the consumption of handloaded 38, 40 and 45 here it is easier to buy 9mm than to handload it a lot of times. Factory 9mm is reliable, easily makes Minor PF, and is plenty accurate for action shooting. I do like the reloaded 147's a lot better, but finding the time to load them at a low savings rate is hard and especially hard when I cannot buy the 40 ammo I need for my Limited/L10 gun, 45 ammo for L10/SS, etc.
