I need some input from experienced shooters of the Glock 20. I need powder and load suggestions for 180 and 200 grain JHP reloading. I hear 800x, or Blue dot, or Pistol power are the best powders and I am totally lost. I am looking to achieve 1200-1350 FPS on the 180 gr and 1150 to 1250 FPS on the 200 grain, also wanted input on the best bullet source XTP?  Gold dot? or?? and how important is having a bonded core JHP, I have always held the belief that heavier is best as long as you are getting enough FPS... HELP!!!! these are for defense/bear loads
