Excellent advice all the way around.
Always check the bullet shape. Different manufacturer, different bullet shape.
For example, a Falcon Coated 9mm 147 will need to be seated deeper than a Blue Bullet 9mm 147. At 2.5gr of Titegroup and OAL of 1.09 my Power Factor with a Falcon is about the same as a Blue Bullet at 3.1 and OAL of 1.11. The profile of the Falcon is noticeably different and will not chamber over 1.09
Also when chasing the Power Factor requirements in IDPA I’ve found its best to chrono shooting weak hand (support hand) only. This lets me know wether or not the gun will cycle properly when shooting a stage when it requires strong hand or weak hand only shooting.
Keep track of everything, even the loads that don’t cut it. I have numerous loads that I didn’t feel were accurate enough or didn’t cycle properly every time during testing that are lodged with descriptions of their failures.
