Let's go 24.5, 24.8, 25.1, 25.4, 25.7

Load 3 of each. Paint each group with a different color sharpie from tip to ogive.

Put your target at your longest distance available. Not over 600 yrds though. Better if you can't see the group developing

Use a large sheet of white paper with one aiming dot in the middle.

Shoot the first one of each group of 3. Then the second then the third.

You should be able to see the color around each bullet hole. I kind of Mark each one with the color where I can look at it and evaluate. You are looking at vertical dispersion. Don't worry about horizontal yet.

Send us pics.of that and we.will tell you what to do next
