In a 24" bolt action barrel, nodes are probably close to 2960 and 3050.
So since it's an unknown bullet-etc combo I would start at a 30.0 gr of LVR, which is below "2950", go up by 0.3's; and try to get up to max at 3050, shooting over a chrono.
You don't' know what your barrel will do, MV-wise, with the combo until you get some actuals.
The loads I just came back from the range with, I calculated them to be 2685 MV and up, but the first set went 2724 instead. Then up from there. ACtuals were noticeably faster than calculated. It happens like that, so start below what the data says you might see. That was their barrel and their lot of powder, their brass, and primer. Lots of variables to vary as compared to your setup.
