most shooters do "ladder tests". This is to start w/ a load combo that has some good history. You load 2 or 3 rounds increasing in powder charge and fire them , preferably at 300 or so yds You will find groups openning and closing as you go up the "ladder". Your best loads will be at those "nodes" where the groups close up. Seating depth and such can be fine tuned at that point. A few shooters only fire 2 shot groups(group size wont get smaller after you fire the first 2 shots). The longer range you can get for work up the better. After preliminary w/u then stretch out to 1000yds. Some reliable loads can be found on www.benchrest.com and www.6mmbr.com
