Thanks for the suggestions. I want to get the most velocity as I can. Looks like you all change powder first then seating depth. I'm just scared my optimal powder charge will be right at max and changing seating depth might increase pressures. I got my groups to 0.6 in now maybe changing powder charges and/or powders will get me under 0.5 in?

I am having a shoot out in a few months out to 500 yards with coworkers who all have remington 700 sendero. I can't lose.
