This was my favorite load when I had my 6BR. Work up your load as rifles differ.

Lapua brass, 29.8 grains of varget, cci br4 and a 105grain Barts Hammer 12thou. in. works everywhere from 100 out to 1000.

105g Berger hybrids or 105g Barts Gungnirs at .009” off hard jam, on top of 33.1gr of RL-15 in a 6 dasher with .132” freebore and a no turn .2715” neck, 1:8 or 1:7.5 to 8.0 gain twist cut rifled barrel. Personally, I only use Lapua brass and have DJ’s Brass hydro form them (although both Peterson and Alpha brass have worked well for others and don’t require hydro forming). The most accurate load I’ve even shot at 600 yards. Hands down.

I have not tried VLD in the 6BR, but I heard that they are fussy to tune. I can’t find Berger Hybrids, so I’m using Lapua Scenar L, what I’m finding is pick a powder charge and stick with it. Low SD etc, then work with seating depth. My experience is within 6k is where you will find acceptable accuracy nodes, so I understand that it’s small, but run testing with no larger than 2k-3K difference between ladder steps. Otherwise you will miss your node and be testing large groups and wondering why nothing is working. I think the best method and money saver I have found for developing a load is finding the lands or Jam with multiple methods, and then seating them back 2-5k, to avoid sticking a bullet and loading up 50 rounds at a max length, bringing them All to the range and then using a KM Arbor press to find the seating depth. It will save many trips to the range. Saves time/money. It’s also the best bullet seating Press for concentric rounds.

The 105gr Berger VLD aren’t that hard to tune, but certainly the 105gr Berger Hybrids are easier to tune. Both will shoot quite well from Jam to .020” off jam. The VLDs have also been known to shoot pretty good jumping them (which I’ve never found any success in doing). I totally agree with the seating depth info above.

My 6BR likes the Berger105 Hybrid.
30gr Varget, seated .010 INTO the lands.
2840fps, 58 deg F, 29.33 station pressure, 80% RH
Lapua brass, no turn, BR4 primer.
.196 3 shot group at 100yards.

@Link Im not patronizing as I’ve been guilty of doing this same thing in the past, but moving forward, never chase a combination like that.
I shoot 20 rounds into the dirt with new barrels and then do 15-21 rounds of seating work and 15-21 rounds of powder. If it’s not working at any point, I make a change. 6BR shoots so well that you can tell if it’s working before the depth test is over.
Here’s a few things….
If that VLD isn’t working at jam, 10 in or 10 off it’s probably never going to work.
Varget is highly overrated. If it isn’t consistent at 2725 or 2825, you may be able to reach the 2880s and they fly well right there. But again, overrated in my opinion.
You’ve gotta go one way or the other so maybe try N140 or H4895, both of which are faster, or try N 150. I don’t think I’ve ever had to change bullets to tune a load. Primers either…
As obvious as it sounds, give the gun and scope a thorough look, even the inside of the bolt.
Best of luck!

I'm a complete novice but I'm learning. Currently using Berger 150Hy .018OTL, Lapua cases, CCI450. The load shoots reliably under an inch at 400yds. Not an eye opener for you guys but at least I'm started.
I've also been fooling around with the Berger 65BT in my 8 twist .150FB bbl. The shorty bullet is .150" off the rifling but shoots surprisingly well at 400yds when conditions are favorable.
Yesterday I shot 3 consecutive 3-shot groups that came in at .46"-.56"-.62" at the 400yd line, which actually measures out to be 417yds. Charge is 31.5gr Benchmark. I literally can't hold any better than that. The crosshair is always moving a bit, despite my best efforts.
Question: I have only used CCI450 primers for the 6BR in a Lapua case. However, I see that most of you have posted loads using a CCI BR4 primer. Is there a distinct benefit to using the less powerful primer?

In the limited amount of times that I tested these primer against each other ( in my 6br) the only difference I could see was the price of the Br4 vs 450. JMO

Here's where I get confused. I thought "jam" was as far out into the lands as you could possibly seat a bullet for given neck tension?

Really depends on your rifle. You could test the BR-4s with your load but you may not see any improvement in your groups. Sounds like it is doing well as is.

I really doubt that I can improve the groups with the 65BT because I think I'm at the limit of my personable ability. However, the 105Hy could tighten up a bit. LOL
I don't have any BR-4 primers here but I've got Fed 205M primers. Anyone using them in their 6BR?

It is, the way I would define it. Like the length that a bullet would be if you forced the bolt closed and then ejected the round and measured it.
So yea.
