My wifes cousin wants to take me and his dad out shooting on Tuesday and asks me to bring powder coated and PB gas checked bullets to test out for accuracy. Ive spent the entire day getting bullets lubed, Powder coated, gas checked and was about to start loading when I had a thought.... I have to measure the bullets!

My 9mm 356124TC bullets are .562 - .565 (depending on if I scratched the top first..
Powder coated measure .575
lubed and gas checked measure .585
Powder coated and gas checked measure .595

Doesnt sound like much but in a 9mm case Im thinking I need to adjust seating depth .01 up as I load them.
What do you all think??
I hope I can find my chronograph before tomorrow night, I want to see if the fps stays consistent by doing that

As long as you aren’t loading too end loads I wouldn’t worry about them, the velocity difference shouldn’t be too much. However, I don’t know your powder charge or what primers you use or any of that.
