Lapua case weight difference

[dansig]

Hi
I am new to this forum and new to benchrest, I just had my Howa 1500 .243win changed to 6mm BR Norma with a Krieger barrel with 13.5 twist.

now it's time to reload and from what I've read the case volume does matter when it comes to accuracy, so I bought some Lapua cases and took a very close look at width, weight and length.

Lapua 6mm B.R. Norma 100pcs Lot: P00545002
I found no difference in length or width but the weight was ranging from 125.8 up to 128.2gr

since I am new to BR I have no idea how much attention I have to pay to the case weight so all help would be appreciated on reloading info.

btw. I'm Icelandic so if I misspell some words it's because I don't know the correct spelling

Is that all of the brass that you have for right now.. if so.. after prepping the brass.. shoot them in this order from the heaviest to the lightest.. should be fine..
