Where do I really need to start in determining what factory load to use? By my reckoning, it would be shape first to determine feed reliability. Then bullet weight and velocity for cycling, and then manufacturer for accuracy and consistencies. About done with break in on the full size 1911 that I will be using, and need to start determining ammo. Right now I am grabbing what I can get a hold of, but will need to settle soon so I can sight the pistol in. I don't want to rush it or waste money.
