I have the drop data for 600 but I dont think its got enough punch out that far so will limit myself to 500 yds.
I use Remington Brass, Winchester large rifle primers, AR2208 (your Varget), my load data is out in the shed but its about 45 gn. I use only 120gn TSX.
I have to re-chrony them as my mates chrony is a bit dodgy but the reading I got was 2932 which is not fast- but very accurate. Will re-check velocity now I have a new chrony
