6 Dasher 109gr N150 Load data?

[Redfoxcreed]

Hello guys,

I'd like to know if some of you have load data's for The 6mm Dasher with :

- Alpha brass and Lapua brass.
- N150
- Berger's 109gr

Thx

 

[Redfoxcreed]

Ok since no one wanted to participate here is some data.

After a quick speed/pressure test on my virgin barrel I started at 31.8gr of N150 that landed me at 2818 fps.

After 200 ish rounds the same load was pushing 2842 fps and after 300+ at 2861 fps.

Now I’ve dialed everything back once I’ve figured that out .

Here is 30.97gr of N150 at 0.066" from the lands ( 1.779" cbto) - 2814 fps average

nice!

The only thing that make scratch my head is carbon on shoulders.

Virgin brass are pristine without carbon on the shoulder. Just like half the neck. But once fired FL sized show carbon on the neck and shoulder

before you guys ask it’s a Forster FL honed for Alpha brass (0.266NK) and I bump the shoulder only 0.002".

In fact the 3 pictures you see is a test . First is virgin brass , second is 0.002" bump and last is 0.003" bump.

Anyone has experienced that on a Dasher ?

I experienced the same thing in a 6br. Still haven’t figured out Why

Here is an observation that may save you some time, frustration and $$$s. I have run N150 in a couple of 6mmBRs with awesome results. I thought that since the 6 Dasher is based off the 6mmBR, N150 should be great! Having said that, I have tried it UNsuccessfully in 3 different Dasher barrels. I have no idea why this anomalous phenomenon exists>>BUT it does! You may continue to try>>>>and if you succeed it would be excellent and I would love to see the results.

Are you referring to the carbon ring or something else?

because I can say I’m really happy with the performance so far of the N150. Accuracy is good and ES… Just the weird carbon on shoulder with once fired brass since I switched to the Forster die.

 

[ShootDots]

I am referring to the inconsistent accuracy I got in those barrels I tried N150 in. Varget, and RL-15 have ALWAYS proved to be the most consistently accurate powders in a Dasher. I also found VV N540 to be their equal, however, it will eat throats up like candy!

 

[Redfoxcreed]

Varget is so hard to find.

Do you think the IMR 4166 or 4451 would be a good/better fit? That the only thing left I can find here.

For me N140 works in a Dasher.

I do not know.. I can only give you good info from my own experiences or from people whom I trust as excellent loaders / shooters. Nobody I know shoots those powders. That does not mean they are not good alternatives>>>I simply have no experience with them..

I have collaborated with Ben (Shootdots) for years on everything reloading from brass preparation to final results on the target at mid and long range In a number of different calibers. He in my opinion is one of the consummate sources of accurate information on this website. You can trust his advice as being offered from solid experience.

I’m shooting 109’s in a BRA and not a Dasher. My load is 31.5gr of Varget, 2.410 COAL. It goes 2900 out of a 26 inch barrel. I found some 4166 so decided to give it a try.

31.5 IMR 4166 at same 2.410 COAL goes 2920 and while I haven’t tested or played with the load yet, it was shooting 1/2 inch 5 shot groups for me. The brass had a little ejector shine on it, so it seems to be -slightly- faster than Varget, but it’s clearly slower than 4895 which I get pressure way down at 30 grains when shooting 109’s.

All in the BRA, not dasher, but could be worth trying if it’s all you can find.

2900 fps definitely look hot to me , I’d be happy with a mid 2800 fps but I think I’d like to test it out. Look promising
Does it burn clean?

I do really appreciate his insights. I’ll hunt Varget but Over here there is none available anywhere.

ill have to stick to replacements

I haven't shot enough of it to really know if its any different than varget of 4895. 2x5 groups isn't a lot of data aside from pressure testing it so far =)

 

[Redfoxcreed]

Finally been able to get my hands on 2 lbs of Varget and 1 lbs of 4166. I’ll be able to test it out !

Hello everyone, thanks for all the good infos I got here just lurking.

I have a 6 Dasher barrel coming back from my riflesmith this week-end. I'm new to this caliber and intended to switch to N150 for this new 6 Dasher and for 6BR as I'm running low on Varget.

Seeing the speeds posted by Redfoxcreed, I'm a little disapointed as I was hoping 2900+ from a 30inch barrel. That said I would choose precision over speed any day.

There's very little out there about N150 unfortunatly, besides what Redfoxcreed posted.

ShootDots, could you tell us the charges you were using with N150 in the Dasher, and the speeds you got?

I will use Alpha brass, Berger 108 and probably CCi 450 for now.

My reamer is a JGS #1300 (Kiff design) but throat is being cut for the 108. Barrel is a Krieger 1-7.5, 4 grooves, 236 bore.

Thanks!

Naf

Will defer to @ShootDots experience but may be able to help. I am running a straight BR on 30.6 grs. N150 out of a 28" Krieger HV 4-groove barrel pushing a 105 Hybrid Target at 2850 fps. No pressure signs at all. Could likely squeeze more velocity out of it but it is not really a competition rig. Here is a target I shot with it last night:



I would expect that a Dasher would take 1 to 2 more grains of this powder to achieve around 3000 FPS--somewhere around 32.3 or 32.5 maybe...

I have found N150 to be a fantastic powder. It's great with the heavy 90 grain VLDs in 223, the 200.20X in 308 and now the 105s in 6BR!

Sounds like you have a fun project coming your way... Good luck with it.
