Velocity drop during ladder test
I did a 10 round ladder test of .223 through my bolt gun and had 2 rounds in the middle drop in velocity. Is this normal. I am new to reloading but paid attention to my loads.
Shooters world Precision powder
Lake City 5.56 brass
Sierra 77 grain TMK
COAL 2.318
Starting charge 22.2 gr
Final charge 24.0 gr
Any help is appreciated!

I’m curious to know how much drop in velocity you observed. Also, What chronograph are you using?
