90 gr Bergers and Varget

[6BRShooter501]

Has anyone shot these in their 6br, i shoot 95 VLDs and Varget regularly but have never heard of 90 grainers until i picked up a box today. If youve shot these what was your load data? Thanks

Start at 29.5 and work up. You should find your node pretty quick. 90's are pretty easy to tune. Mine likes the about .005 jam.

My 6BR Cooper (1-10 twist) likes this bullet with either Varget or V-N135.

Interested in your results with the 95's. I shoot the 80's and 105's with great results. I have a few boxes of the 95's but never put any fire behind them yet.

 

[6BRShooter501]

The 95s are my go to bullet in my 6br, there extremely accurate at 100 and out to 600, i have yet to find a bullet with such consistent accuracy in the 6br, thats why i use these for all my varmint hunting

I did a search and didn't come up with much. Like said 6BR 1-8T Varget.
My friend gave me a box of 90 gr Bergers
and I want to try them at 300 - 400. Anyone had luck with this combo? If so, what was your favorite load?

ps I do shoot 105 - 108s at 30.3 gr.

6BR 31.0gr of varget with the 90 berger. Work up but not excessively hot in anything I've shot that in. It's been a "go to" load for me in that combo for a while. @Shooter13

If you're married to Varget, simply ignore my advice.

If not, give H-4895 a try with the 90 grain Berger. I did and I'll never go back to Varget.

So on a whim I load up 5 of the following. 6br 1-8 twist
No testing. 66*, 10 mph wind 1 flag, This as good it gets, at this 200 yd range. Bergers just touching. We will see if it repeats.

How many grs. of H-4895 did you settle on. Thanks, Ron.

Lapua (gold box) brass, 29.3 grains of H-4895, zero jam with a BR4 primer.

Hope this helps.

90s at 300 - top target, Varget,

Don that's lookin pretty good.
I've been thinking about a lil slower twist with with a .045-.070 freebore and running 80gr Bart Dominator for 300yd an in.
FWIW the Bart's are cheaper than the Berger

I think about .090ish is about ideal freebore for the 80's in a 6BR. The common .104 is close enough and works just fine as well. Not sure about Barts 80's but the berger 80 fb and their 105 vld both have very near the same bearing surface. So a freebore for their 105s works very well with their 80's also, fwiw. Been using .070 in a 6 Grendel for several years now but the neck is shorter on the Grendel than a BR. That long BR neck is very forgiving to freebore. The grendel neck is roughly .070 shorter than the BR neck, IIRC. But the .070 freebore works well with a wide range of bullets in that case, from most 65ish flat bases all the way to the 105 clss bullets. Just more critical to get right than the BR neck is all.

90s at 300 - top target, Varget,

The 90 berger and 31.0 grain Varget load is pretty tough to beat IME and that little bullet tunes up easily. Good shooting! Have you chrono'd it yet? IIRC, it is around 3100 fps. I think people get too caught up into BC when that little 90 isn't leaving a lot on the table to the higher bc heavier bullets when you factor in the extra roughly 250 fps. Same for the 95 vld but their bc is a bit better than the 90's. The 95's seem more finnicky to tune though, at least IME. If ya run the numbers, a 95 vld at 3100 vs a 105 vld at 2850 is dead nuts even in wind drift, fwiw. I think more people should test that weight class in their guns rather than jumping straight to the 105's in the small BR variant cases. JMO though.

Mike Bart's 105 sits out there a bit a d with the 80 being shorter my mind tells me freebore should be shorter to accommodate.
Pictured from left 105 Bart's hammer
Berger 90gr, Bart's 80gr Dominator, the Dominator does appear to have more of a tangent ogive this may seat it in the neck enough to run a .104, ill have to build a dummy to be sure.
The cartridge shown is at .012 jump
FWIW in conversation with Bart he informed me that the 300yd 4 target agg record was shot with his 68gr Ultra.

He can probably tell ya based on his bullets. But yes, with the bergers, their 80 vs 105 will both work well with the same freebore length. Curious how different his are. Build a dummy and let me know. Is the dummy there for a .104 freebore or what? Some have been going longer for the heavies to keep the boat tail out of the powder column more than a 104 will.

104 I believe Mike the base is right at neck shoulder junction there abouts.
I'll build a dummy after I load for Thursday's club shoot, my seater is set on hammer and I don't want to move it yet. lol

I don't know what my fb is but I have about .263 of bullet in the neck not counting the boat tail. I'm just touching the lands. The reamer was for a 105 - 108 but if it works who cares,;{}

Correction .200 of bullet in neck not counting boattail.
Sorry

If I get a few minutes and remember, I'try to do the same with a berger 105 and a berger 80, just for reference in a 6 Grendel. Not the same but will still give an idea as to the difference. Just to be clear though, yes, the boat tail will be below the neck junction, especially in the Grendel. I was referring to the bearing surface area and keeping it above any donut area with both, the 80 fb and 105 bt. You can look at the bullet specs on Bergers website too. Here's a link. Ya gotta do a little bit of calculating and the chart is more reference than anything. I've seen the actual product vary quite a bit from the chart, fwiw. A dummy will show the whole story though.
