Just chiming in to clarify that yes, Berger's data is 2.800" COAL. Not only that, but their data is derived from Quickload, not pressure testing and I've found it to be cautious and conservative to the point of unuseable. Their max (I own the manual and have loaded their bullets for 6 years using the email'd data before the manual was published) for the mid-size cartidges is usually 2 grains or more lower than Hodgdon's data. The velocities derived in real rifles at Berger's max for 308, 260 and 243 in my experience is laughable and will not allow you to be competitive. All this is just one man's opinion, take it or leave it.
With that said, I agree with the others that 45 grains of Varget is too much with a 185. If you're not seeing pressure signs, good for you, but I think at 45 grains your brass will wear out quickly at the very least. I'd like to know what kind of velocity you're seeing. I wouldn't go that high with that combo.
Looking at your targets: load wise I would concentrate on 43.2-ish and 44.4 only if I felt I had to. I personally wouldn't be comfortable running more than 44.5 on a regular basis whether or not the groups look good based on my past experience with 185 VLD's. For me those shot best at 43.0, but I was loading them at 2.82" OAL and they're of course a different bullet.
In summary I would try 43.2 and test at different seating depths.
