I got this on my wifes 243 with min loads. I anneled the brass and raised the powder load. It seemed to fix it the closer I got to the max for her gun.

Maybe the powder is a slower than normal batch . I am trying to finds reasons for low pressure as the load weight seems ok .
Only you can tell if it's safe to bump the load up .
I would also check for a carbon ring in the throat area , dirty brass , dirty chamber , no chamfer on the outside of the case neck after trimming ,
VLD bullets don't like to jump too far to the lands
