Hey guys hows everyone doing? My question has to do with my laziness. I have been shooting a 7 ultra with retumbo and 160 grain sierra gamekings, and I want to start shooting the 168 gr matchkings with the higher ballistic coefficient. What are the chances that the load that has been working with the gmking will be close to right for the mk bullet thats 8 grains heavier? I guess I'm hoping someone will say they will be right about the same so I won't have to go throught the work up phase that takes so much time. Thanks everyone!
