I'd have to agree with CCW. Until your skill is extremely high, your ammo selection will be secondary. (unless you plan on shooting your hand gun off sandbags for 50yd groups). As you become better and better with a given pistol, you'll have time to figure out which ammo groups better to your poa. If you are shooting 10" groups at 10 yds with WWB, don't look to ammo to solve a mechanics problem.
Good LORD! You typed exactly what I wanted to say, but couldnt! LOL!
