Every gun is different ..... But VLD's like to be jammed. I promise I'm not steering you wrong.
To find the best results your just going to need to test.
Take note as well that over time due to wear n tear the gap to your lands will increase. You will notice accuracy drops over time and will need to "chase" the lands. Were talking over a long time... 2-3000 rounds. If it gets to bad you just re cut the barrel chamber.
Your bullet does not touch all the lands right away at the same time. Think of your rifling like a screw, one land will kiss the bullet first. I think this is why the narrow VLD's like to be jammed.
Ps. Bergers rock.
