    I just got my hands on some H 1000 and my 210gr hunting vld's. Because of the freebore I plan to seat them .0015 shorter than the mag well. What is a good starting charge and how many grains should I increase per group? Was planning on half grain differance per 3 shot group to see which load groups the best. Lastly, other than a chronograqh for checking ES, which I dont have yet, what else should I do in my load development to find the most accurate load?
