We tried 31.3 grains Varget, CCI 450, with 95gr VLD bullets seated about .012" into the lands. This shot like a laser in a PacNor 3-grove 0.236 bore. Sorry, no chron data.

Sorry I do not hold good record on seating testing now. This was ~10yrs ago(2 computers), and my '6br log', which is a spreadsheet, seems fragmented. I just checked goto GHog ammo against my MAX OAL reference round. It appears that I settled on 5thou INTO lands.
This is not 'jammed' per say in that there is no hard seating goin on. But it's well into touching.
Odd for me, as I typically stay away from jammed even if it means changing bullets..
But in this case it must have been most accurate.
I recommend Berger's procedure, as I highly doubt jammed is 'always best' for VLDs.
You just never know until testing it.

I run ~30.8 Varget or RL15, BR4 primers, jumped .040" in a 26" 8tw Krieger. Runs about 2950fps with SD in the 4-7 range. I have also started monkeying around with 8208XBR, more speed with maybe a bit better accuracy, start off at least 1 grn. low and work back up. Still gathering data on that one but it shows promise.
Would any of you guys rate the 95 vld as fussy in a 6BR? Weather dependant I will do a load test this weekend coming so just trying to get a handle on some of the comments as a rule of thumb or if thay relate more to a specific shooters setup....typically the 6BR is very easy to load for....
I don't understand your meaning of 'fussy' yet.
No matter the bullet, there will be a couple settings where it shoots it's best in YOUR barrel. And that best in YOUR barrel, will be good enough, or not.
None of that is really predictable, or we would all know exactly where to seat.
If by fussy, you mean intolerant to seating variances, then I would suggest that yes VLDs are fussier than low cal tangent ogive bullets. This, w/regard to resultant accuracy.
But then I would wonder why the seating variances.. With a suitable die & stem, VLDs don't seem any different to seat (to me).
What do you mean 6brinNZ? What is your thinkin?

Mikecr - fussy in the context that it is difficult to get to shoot accurate and difficult to keep it there. Whether that be powder/mvs sensitivities or SD sensitivity. I only ask the question as there seems to be some comment with respect to the Berger 95 VLD specifically.
Reading the Berger info (http://02b0516.netsolhost.com/blog1/?paged=2) it states for VLDs to try seating depths by up to .120, once this is established the seating depth window can be as wide as .030 - .040. This process seems easy enough and a SD window .030 - .040 wide is fine, so just trying to resolve some of the comments against people that have been there and done that specifically with the Berger 95 VLD as opposed to general VLD comments.
Thanks for your help.

I gave up on the 95VLD for my 1:10 PacNor 243Ackley w/BAT action
The bullets didn't keyhole but they floated at 300 yards - resulting is no accuracy consistency.
Have been experimenting with Berger 88gr. flat base with improved accuracy.
All this happened in the last 10 days.
Hope this info. helps someone.

From what I've read, I think that this particular bullet would really benefit from a bearing surface sorting since it does have a very short bearing surface. For whatever the reason I got an unexplained flier every now and then but I am not a bench shooter, just shoot for fun and with the rifle I'm shooting with, it might just be part of the set up. While testing come ups with this load I shot a 5 shot group at 400yds that measured 3.3" but 3 of the five were .33" and this was in calm conditions with no changes. Just for what it's worth, could have been me or whatever.

Just coron'ed my 22.7" Blaser R8 Varmit Professional yesterday for the first time. Lapua cases, CCI-BR4's, 32.0gr of VV N540 + 2936fps, ES of 12 fps an an SD of 6 fps for ten rounds with the Berger 95gr VLD's. I would like to touch 3000 fps and have no pressure signs at all.
Blaser barrels tend to speed up after about 200-300 rounds through them and I expect this one will be the same and pick up 40-60fps.

When you do the Berger seating method you will find two spots were your bullets all shoot very well compared to your other seating depths.The results are very dramatic and easy to see.
Once you have that number wether it is 0.025 jammed or 0.185 jumped your groups while very good they can still be optimised further.
Get yourself a comparator and seat the bullets to within 0.001 for 5 thousanths on each side of your original number.When they all go through the same hole your all set.
If you vary 0.002 or more on either side of that seating depth you will see fliers.
