Which powder?
Try the ones listed in your manual*. Start at the start load. Follow their recipe. Work up. You'll find that they have done their homework, so you don't have to.......
*Note the type of firearm the manual writers used to develop their loads: my Speer manual (#13) used a 22" barrelled Ruger 77 MkII bolt gun.... trying to duplicate their results with a 16" barrelled AR might be an excercise in futility.........
