Load testing question?

[Colten519]

I'm just about done with my first ever reloads. I'm going to be trying 2 different powders. 4831 and 7828 with 100gr Barnes ttsx. I see people mention ladder tests and such. Would it be ok to just load up lets say 3 rounds going in .5 grain increments to find the best combo or is there a more detailed way. Also note that I don't have unlimited bullets and cases. I have a decent amount but not enough to let's say fire like 50 rounds of each load. Thanks

Three rounds is too few to be statistically significant. Five would be the bare minimum, I usually shoot seven.
