In most post I stated that I have loaded 10 each starting at 24 grains and increasing in .5 increments. If you are asking me what published data I am using it was multiple online posts as well as an Army document showing all of their bullets, starting at .38 special and I stopped reading at .50 cal. armor piercing. Most, if not all unverified respondents, stated that WC844 was very similar, if not identical, to H335 results. Note that I said I said similar to as far as results.
Edit - oops. I forgot to add that I am trying to load to max velocity but max accuracy and reliability.
