It doesn't meter for crap. If you are going to use it, plan on weighing each and every charge. Not my favorite thing to do when handloading pistol ammo.Thanks for your responses, you've all been a big help. It's my first time reloading and I'm just trying to make sure that I make no mistakes and that I fully understand everything thats in my manual.
another quick question- Does anyone have any experience with 800x with 180gr. 40s&w? From what I've read its mostly for large caliber pistols. But again Lyman's has it down as their preferred powder for this weight bullet.
