105 VLD's preferred seating depth? Anyone got some starting info? PRS gun so I'd rather not jam.

From working your way in the lands to out, try:
+.021, +.018, +.009, +.006, -.006, -.009, -.018, -.021

If none of the above show results, try:
-.055, through -.065.

What's your freebore?

What's your freebore?

I'm pretty sure it's 104".

.020 off, and go further away from there.

 

[6BRA]

The BTO on the vld is shorter than the hybrid.....it is even shorter than the 90.....

The Berger 105 gr VLDs worked well in my 6BRX which had .120 free bore. The best accuracy was @ .005 to.007 jam.

Look at the Berger website, they provide recommendations for tuning their VLDs. The 6mm 105VLD Berger Hunting bullet were most accurate -.080” to -.100” for me.

I test all bullets the same by start with a .010 jam and test working away from the lands. Rarely do I find myself jumping more than .020.

How much for you adjust? .002?

How much for you adjust? .002?

I usually do .003 at a time and then go to .001 or .002 when things start shaping up.

SAME for Me with, the Sierra 107 MK's "Tipped',.. Lite Jam, IS Best, in My 6 XC, 1-7. 5, .104 FB with, One grain under, Max Powder Chg. ( Found Max Pressure / Velocity at, .020 off,.. FIRST ! )
I'm getting "BugHoles" in, the 2's and 3's, now !
BUT,.. .035 OFF lite Jam, only shot, 1/2" groups,.. BIG, Diff,.. IMO

 

[Idaho-Lefty]

For My Barrel, there should be, other, Accuracy "Nodes" at, around,.. .040 to, .120,.. Off
Every Barrel is going to be,.. Different.
Might start with, 4 shot groups, every .010 from,.. .040 off.
I use 4 Shots, in case I "throw One" then,.. I still have, 3 Holes to,.. "Look at" !
Three Bullet Holes, "Touching", is a good, "Clue" to, accuracy, even if one's, 3/8 of an Inch away from, group.
I'm NOT gonna, even try to, Improve on,.. WHAT, I got, tho !

I just did a setting depth ladder on my 6bra with 105 VLD Fed 205m and N-140 started at 4ths jam and ended at 36ths OTL shot this wednesday wind was above 20mph bi-pod and rear bag see photo below hope this helps. These are all two shot groups at 100 yd.

My 6 BR prefers a 1.769 CBTO which is about .040 off of jam.
29.2 Gr Varget
105 Vld-Hunting
Peterson brass
CCI 400
Shot a 1 hole 3 shot group at 100 yards at this cbto with a velocity spread of 4 fps. At 300 yards the it shot a 1.31 inch 3 shot group, Theres some promise to this load.

You’re gonna have to test quite a few seating depths. Took me a good while to realize you have to hit these dead on for seating. There’s not a big window like the hybrids or 108s. Start at 3k off and work your way off. I hear PRS guys all the time shooting way off the lands
