I swear by berger
the only problem with vld is that you just take all the books you had and throw them away. get rid of you're notion of oal and start using a bullet comparator.
if you notice the tip of your bullets, they are not perfect. they are actually far to be perfect, can't use that as a reference.
because the vld have a taper so long, its important to be perfect in your round length. doesn't take much to throw it off. not saying you absolutely need it, but a competition die make a damn good job at seating these puppies all nice and perfect.
for how far to seat, I used to go 0.015 off the land, then changed for 0.010, followed by a 0.005
they all shoot great, consistency is what you need the most. the bullet is long, tend to go a bit offset and create some runout. I ended up pressing in 2 stages as t seemed to help a lot with runout.
nowadays I make it so it stay 0.001 off lands, don't know if its the best but I need as much room as possible for powder. . . .
