If your not 100% set on the Berger VLD I would take a look at the Hornady ELD bullets. I have been having great success with them in my .300 however I've been shooting the 178, 212 and 225 rather than the 168s.
As for powder I would look in the burning rate between H4831 and H1000. In my dad's .300 I was running the 178 ELD-X at 79gr H1000, I used it because I have a lot of H1000. His browning can support a 3.5 COAL so that might be a high charge in your rifle so as always work up. Since your running a single shot I would load them out as far as you can to maximize capacity.
I assume based on you bullet choice this is for long range shooting?
