6mm Dasher Loads

[goneshooting]

In my spare time, I'm working on compiling what I can from the data mentioned in these posts into an Excel doc. If you could, please enter future info in this order:
NEW BARREL
Bullet Weight - 105
Bullet Manufacturer - Berger
Bullet Model - Hybrid
Brass Manufacturer
Powder (i.e. Varget, RE-15, N140, etc.)- Varget
Powder Charge Weight (in grains)- 32.4
Primer Used - CCI 450
Velocity- 2,910
Barrel Length 31
Freebore 120

Using the list above, in that particular order, will make creating the Excel doc. much easier. I'm only on page 2 from this thread so far, but I'd like to work my way through all of the pages on this thread. I will provide this Excel doc. to anyone who is interested when it is complete. I'm put another post on here when I've got it done. Might take me a few weeks to get it done (full time job, wife, and two young boys get most of my time in the day), but I'll keep working on it.

How do the br4s work?
I am only seeing 450s.

Have to ask

450’s work great in the Dasher

 

[Liven The Dream]

450’s all I use..

Anyone try Staball Match in the Dasher yet? I'm gonna try some behind a 107 smk soon. I'm thinking start at 31.0gr and work up in .02 increments. I'm expecting to pressure out around 33.0gr.

I can tell you 6.5 Staball works great with the 88 Berger fb

 

[Monday shooter40]

I know you all have been anxiously awaiting this data. Here it is.

-Winchester Staball Match pressures \ velocity tests.
- 6 Dasher. Lapua no turn chamber .150 FB. Proof 26" SS blank. Impact action.
- Lapua brass with CCI 450's
- 107gr SMK ( the old ones!) 1.850 CBTO ( is about .020 off in my chamber)

Test #1
- 31.0gr = 2693 fps
- 31.2 = 2743
- 31.4 = 2750
- 31.6 = 2759
- 31.8 = 2762
- 32.0 = 2766
- 32.2 = 2820
- 32.4 = 2809
- 32.6 = 2844
- 32.8 = 2852
- 33.0 = 2838
- 33.2 = 2852
- 33.4 = 2859
End test 1

Test #2
- 33.0 = 2848
- 33.2 = 2871
- 33.4 = 2916
- 33.6 = 2876
- 33.8 = 2914
- 34.0 = 2925
- 34.1 = 2931
- 34.2 = 2936
- 34.3 = 2940
- 34.4 = 2947
End test 2

5 shot string of 33.5gr, same load parameters as above. Just a guess at good charge weight after test #1.
Avg = 2890
SD= 4.3
Max = 2897
Min = 2886
ES = 11

I was shooting all this at 500yds so I can't really comment on groupings. It never came off a 10" steel plate.

A few of the charges At the upper end started to give me faint ejector marks. Very faint. As always, do your own work ups. I'm sure these powder charges will be over listed max if they ever get to publishing data for this combo.

I just finished putting together a 6mm dasher on a Bighorn Origin action with a Criterion barrel 28”, 7.5 twist and .104 freebore. Will be using Sierra 107 gr. MatchKings and Varget to start testing in the morning.

 

[22vartarg]

Sorry for the late reply, but life takes priority at times. The Criterion barrel is a great shooter. I put it in a MDT Timber chassis and it looks great. This is a 5 shot group at 100 yards .

I just re-read this whole thread, and no one is running N140 or N150 in the dasher. Or at least isn’t bragging about it. I just tried N150 today and I am very interested in this as it shot very well at lower velocities and initial testing.

Anyone else out there using N150?

I’m looking in to N150 also and don’t know where to start. And help would be appreciated.

VV N150 Loads in 6 Dasher or Straight 6BR?

Anyone use N150 with 105 Gr class of bullets successfully? I'd appreciate you sharing your loads. TIA

Schilen 28" 1/7.5 twist. 104 FB, .272 neck.
31.3 Varget, 105 Berger Hybrids. 010" off, CCI 400 primer, Alpha brass.
2875fps, ES 10, SD 7
2 shots at 3 o'clock were sighters.
5 more in the X, .165" @ 100.

 

[rotts4u]

I didn’t see a lot of data on the 110 atip hornady bullet so here is some. Only three shots each and it was pretty cold when I shot these. Bat MB action 29” Kreiger barrel 1-7.5 twist and the data comes from a lab radar. FYI none shot particularly well despite weighing and measuring great. Also lapua 2 fired brass. And I was jumping .030” in a .170” freebore chamber.

Just shot my Dasher today at a practice.
32.0 varget
Alpha brass OCD
105 berger hybirds
cc450
Barrel twist 7.5
FPS 3015

1100 yards it was shooting 8.0 mills
330 to 1100 yards the rifle was shooting great.

That's just about where my node is 33.2 gets me 3080fps with the exact same components as you
