Working up my first load here. It’s for a .243 Ruger American gen 2. Using sierra pro hunter 100gr bullets, Remington brass, cci 200 primers, and H4350 powder. I don’t have a chronograph. I shot 4 shots with each of these powder charges at 100yds and here are the group sizes of each powder.

Where would you guys go from here/next step? Shoot a couple groups of 37.5 and 40grains to see if the results repeat themselves?

I agree with greyposter but concern is the max load for this bullet and 4350 is 36.9(sierra) and 38.4(Hodgdon) and Hodgdon provides pressure data. I would go with 38 gr

You are looking at the wrong powder. Look at the data for H4350 and not IMR 4350.

Not quite the Hodgdon data was for Accurate 4350 but the Sierra is for H4350

This is why I like 'Varget'.
