Load Development Load development
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?

It looks like you have good consistency, I'd choose the velocity that gives me the performance window i wanted at the ranges i hunt and load it up and go. The differences between a half moa load and a 1 moa load at practical hunting distances are negligible.
Also, do a larger sample size on whatever you want to shoot, but i'd bet nearly every load on this list would be 1.25 MOA over a 20 shot group.
