Ok, so you did some starting load charges. Now increase the charge weight by half a grain until you get to max charge to ensure that the bullet/powder/primer/brass combination is safe in your rifle.

Don't let the chronograph tell you what load works best for you. Develop a good load first, then let the chronograph help you make it better by figuring out how to get your velocity SD down if you want to.

That being said, 2100 to 2200fps is not where I would expect good accuracy from 155gr bullets. Mainly because you are going to have lousy case fill, which can lead to erratic pressure curves (there are exceptions to this, but they are rare). I expect you will start seeing better accuracy when you get a better case fill.
