load development questions

[mapper]

I loaded up 6 diffrent powder charges at 0.020 off the lands and headed out to the range, these were single loaded, 10 shot group 100 yds,

i'm going to shoot 2 5 shot groups next with the 24.1 and 24.5 as well as mag length and see where that takes me, primers looked good, at 0.020 from lands.. the 24.1 group had the most consistient velocity spread (29) the graph paper is 1/4" grid, and I did pull a couple of shots , comments welcome..this is out of the longest chamber rifle.

I was trying for a single load to try in a single shot, so that explains why loaded long..
