Berger has seating depth Recommendations on there websight.
Following them will save you time and money.
What you should think about is that if you run the bullets in the lands.And push them up in hard enough.Eventually you will,someday, have to unload a loaded round.If the bullet sticks in the rifling.You have a mess on your hands.I typically avoid doing that on my hunting and target rifles.
Sometimes especially with VLD bullets stuck up in the lands they shoot very well.So its suductive.But sooner or later you will get burned.
Just looking at your loads.Ive seen that pretty often.
The "ideal" is that as the powder charge increases the velocity goes up as well.But give or take .2 of a grain of powder isnt enough of a change to really show what your getting.
I would change to .4 of a grain and look at primers and bolt lift.
Most book maximums are lawyer safe.So I would not get to excited about blowing the thing up.
Sooner or later you will get pressure.
Untill you get done playing around with the thing wear your saftey glasses.
A chronograph tells you one thing and one thing only.
How fast its going.
The speed the thing is running is actually irrelevant.
It always boils down to how well it shoots.
Period.
kinda nice to get some case life as well.But in the end it has to shoot accurately.
You did not say what this rifle is going to be used for.
If your just messing around VLDs are a good way to pass the time.
For hunting big game there are much better bullets than VLDs.
For pure target work VLDs are a PITA as there seating depth sensitive.
I pretty much give the VLDs a pass for that reason alone.
Hope this was helpful.

Only accurate rifles are interesting.
