Best powder for hot loads in 180gr and 200 gr JHP for Glock 20

[northbound55]

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

northbound55, Welcome to the forum!  I would suggest LongShot or 800X to achieve your goals, look in the 10mm pull-down section at the underwood ammo for the weights you wish to load.  Take notes and understand the loads are shown but you assume the risk!
The data can be found here;

Also understand that you need good chamber support and RSA to take full advantage.
