Hello all,
I have been using published data to load 55 gr cast .223 with 19 grs of H335 with great success, in an AR-15. I do not have a chronograph, but am happy with firearm function, performance and range results.
I have acquired an MP mold, for 65 gr. I have not found published data for 65 gr , using the H335, that I already have, as of yet. How do I determine how much to reduce my H335, to compensate for the 10 additional boolit grains, and be in the same ballpark, data-wise, as the 55 grs?
I do understand that there are calculators, that can take all of the input and project expected results, but to be honest, I am a technological dinosaur, and for the life of me, I don’t understand a great deal of it.
Any help would be greatly appreciated.
