I use almost the same method but I use my cronograph to find the best SDs and Es.
once I have a real consistant velocity then I play with seating depth to improve accuracy or
different bullets of the same weight.
While working up loads only change one thing at a time or you will never know what change
made the differance good or bad.
Keep good records and analyze the results after each range session and note every change.
At some point it may become obvious that you have a problem with the rifle instead of a
poor load if you can't find a good one.
