Here's the reason to do ladder tests. I found some reloads I had to tear down, but decided to send them instead. 35 grains vs 36 grains same powder batch and all. The higher charge wasn't showing any pressure signs but instead caused the opening of groups.

If you repeat the test with both charge weights, you'll know better if the lighter charge is more accurate than the higher one. Comparing a 5 shot group against a 8 shot group will show the more shots you put into a target, the larger the group size will get
from a 5 round to a 10 round group, the group size will increase 30%
from a 5 round to a 10 round group, the group size will increase 30%
