Have .308 Rem PSS .308. Using for 300/500/600 yd F Class matches. Leo 9x24 scope
Loading 43.0 varget with Fed BR primers, 168gr SMK
Doing well.
Cases are Fed Match 3x fired 2.008 w/o primer seated.
Found I had over bumped the shoulder on 200+ cases reading with a Sinclair gauge 1.605-1.602
The other 300 cases are 1.6075-1.6085. Some are a little difficult to seat so planning on bumping those back .02 and to 1.606 then refire-form them and go from there.
Trying to take out the variables as much as possible.
My first run for the season gave me 300yds-186-7x, 500yds-184-3x, 600 yds 1x (winds were awful and varied each 200 yds...)

Should I keep the cases separated? Or doesn't make any difference?

Appreciate input, thanks!
