This site has user data that can be sorted by powder, bullet weight, and mfg. It is NOT factory data and should be used only to give you an idea of what others are doing. As with any suggested load, factory or not, reduce the charge and work up.
I'll just add that depending on whose brass you're using, Varget may not be the best choice. I found that with heavier cases that have less capacity (Remington), I could not get the max or near max loads to fit in the case. Varget shot well for me; and, if you're not too concerned about getting the most velocity from your load it'll do fine. But I found that with R-P cases, it was impossible to get the max load crammed in the case, or even a grain or 2 below it.
You didn't state the type of rifle (Bolt action vs semi-auto) or barrel twist rate - these factors will influence your powder loads.
My rifle (a Cooper .223 bolt action, 1 in 14 twist 24" barrel) performs superbly with 24.5 to 25.5 grains of Benchmark, using the Sierra 52 grain Match Kings, as well as the Sierra 50 grain Blitz Kings. I know of others who use similar loads with good results in a Savage 12BVSS (1 in 9 twist barrel).
Velocities are in the 3150-3300 fps range.
I seat the bullets .015" off the lands, although that seating depth will result in a longer C.O.A.L. than listed in the reloading manuals.
The cases I have used so far are Black Hills Match headstamp (reloaded from once-fired factory ammo). I don't know who manufactures the Black Hills cases. My primers are CCI BR4.
As usual, it is advisable to start with lighter powder loads and work up, always looking for signs of excess pressure.
