6Dasherfan, what is your barrel twist? Thanks, George

 

[BoydAllen]

AckleyImproved,
Interesting barrel contour. Details? Reasoning? Brand? Weight reduction?

Contour is HV. Lilja 3 groove 1:8. Reasoning on the fluting. I wanted something different to normal boring fluting. The flat flutes look great. It is 28" long also!

Cheers

Dasher load; 115DTAC- 33 gr. RL-15 Wolf SRM jumped .010+ first three groups mid to low 1's ...it hammers ......jim

 

[RDavies]

RE15 is non existant here at the moment, with non expected in the next few months. Has anyone experimented with VV N550?

Did very little load development yesterday for my dasher. Weather was horrible (rain and wind), so I wasn't able to set up the chrono.

Lapua 6BR brass fireformed by jam. (30.0gr Varget with 105Amax)

most accurate load I found in my limited testing so far:
105 Amax seated to touch the lands
33.0gr Varget
FED 205 primer (non-match... just the standard 205's)
Shot 2 groups with this load at 100yds... both were at about .24"

My barrel is really short, considering most dasher's use 26" or longer barrels... it's 22". It seems to shoot well at 100yds, but I'm not sure about longer ranges yet. Will post chrono data for the short barrel as soon as I have it. Hopefully this week!

Just ran the 115's over the crony, ave. 2886 over ten shots with 33 gr. of rl-15.Seems slow but ran the numbers over JBM and it shot 5 clicks flatter than the chart said. It shot a .825 group at 500 yds and shot inside my 6.5 x 47 with 130's for wind........jim

 

[benjamin199]

28" Krieger 8 twist.
Lapua Brass
CCI 450
33.0 gr RL15
Berger 108 BT jammed .010
2950 fps, 20 shot ES 15 fps, SD around 4.
500 yard 10 shot group vertical .21 MOA, Horizontal .53 MOA
No signs of pressure in my rifle.
*note update 7/19/2010 the above load worked well in cooler weather, I have had to drop to 32.5gr in hot weather to maintain the same velocity and pressure levels.

It's funny - in the past I never had good results with #450 primers as an accuracy primer in smaller capacity cartridges (i.e. 6mmAR, 6mm Turbo 40, 6mm BR, 6.5 x 47 Lapua) yet I see many saying that's their primer of choice with the Dasher. Is there a verified specific reason why the #450 primer is a "best choice" vs a non-magnum primer (i.e. BR-4, etc.)?

Prior to this I have always avoided the #450's like the plague because the accuracy I obtained with them never seemed as good or as consistent as with other non-magnum small rifle primers, and I just cannot reconcile things here.

That's the only primer I ever use in my 6.5x47 Lapua, and I have been able to achieve great accuracy with it, so I'm keeping the CCI450's as my primer of choice. Going to use it on my new Dasher as well!

RCW3, I shot side by side test with BR4 and 450 CCI primer at 600 yards from a rest with the 6AR Turbo 40 degree and impact and groups size were the same (very good). Powder was R15. These were 5 shot groups under 1/2 MOA.

I shoot 205 M's.

I see no reason to try anything else......

 

[Bob3700]

Wolf SR Mag primers exclusively.

The Fed 205M's pierced on my rifle on too regular of a basis. My firing pin was bushed by Ger-Tan so that was not an issue.

The Wolf's have given me very low single digit SDs. That works for me.

As for primers, my 22BR, 6PPC and now Dasher prefer the Russian SRMs (Wolf or PMC).
To get my 6x47 to work, I had to use 450s, I got more occaisional low fliers when using the Russian SRMs in the 6x47. I bumped the load up a tad when using the PMC primers and down a bit when using 450s, to keep the same velocity node, so I was only testing primer influence.
I use 2208 (Varget) in my Dasher but 2209 (H4350) in my 6x47, so my inexperienced ameture guess is that the short powder column/ faster igniting powder of the Dasher, will get by with a mild primer flash of the Wolf/PMC primers. With the longer powder column/slower powder of the 6x47, it prefers all the help it can get from the hotter CCI 450 primer to stop occaisional low velocity shots.

My p.dog load was H335 with a 60g Berger at 38-3900 fps.......Start at 32.0g and work up!

This load smoked p. dogs way out there, and shot as well as my 6PPC's. I jamed the lands hard with this load and 7 1/2's ONLY!

I shot many groups in the zero's with this load, and the CCI450 opened up the group by what I could see about .050, which is a lot when all the bullets are basically opening up a single bullet hole.


It amazed me at how clean H335 burned in this case with this amount of powder. My shot strings on p. dog towns was 300 rounds. I was shooting 26-28" unturned Hart blanks. I could shoot 125 rounds or so, pull the bolt and look down the barrel and not see one bit of unburnt powder in the bore, found the same thing on shooting h335 in the 6 BR with the 60's. I set the barrel back a couple of times and basically got 10,000 rounds out of a single barrel. At the 10,000 round mark, the guns till will agg in the .385 area, but due to fire cracking, the copper fouling is a bitch to get out...I was wanting to try something new by that time anyway.

While zeroing for an upcoming match, I stumbled on a load that bears further trial. The load is 32.0 grains of Re 15/Fed 205 primer and Sierra Match King 107 VLD that is seated to jump 0.010. The rifle is a BAT Mod B with Terry Leonard stock with a Bartlein GT (8.25-7.75). The scope is a 36XSightron.

Saw your recent Dasher article in PS magazine - nice job! One correction, the Dasher is not really a 6mm BR with "the shoulder moved forward .100 inch" (the 6mm BRX is, but not the Dasher).

I have a Dasher reamer print and other things on a web page I just set up for the 6mm Dasher at

http://www.6mmhot.com/6mm_Dasher.html

Regardless, the Dasher is a great cartridge and thanks for providing more information about it to shooters.

33.7grs RL15, Lapua Brass-5X fired, Wolf primer, New orange box Berger 105 Hunting VLD's, jumped .0020...31" Krieger Barrel, Panda F-Class action...I DO NOT recommand this load for your gun..it works for mine...33.3grs was giving me 3054fps, but vertical..I started at 31.8 grs and worked my way up until 33.7grs where the vertical disappeared.... I now have less than 2" vertical at 1000 yards..The old Berger(yellow) 105VLD's shot jsut as well but at 33.3 grs...

 

[flatlander]

I've got three bolt rifles chambered for 6.5x47, and the CCI450 gives smaller groups at 600yds. with RL17 & 130-140gr. bullets than my old standby R 7-1/2 in all three of them. Rifles are: 1. BAT 3L prone rifle in a wood stock w/30" Bartlein bbl. 2. Pierce TG in an Eliseo RTS tubegun w/28" Krieger bbl. 3. M700 tactical rifle in B&C composite stock w/26" Krieger bbl. All are 1:8tw.

However, R 7-1/2s have always given better results in my Dashers than 450s...as mentioned - short, fast powder column vs. longer, slower column probably has more to do with it than anything else.

After some very consistent results with Wolf SRMs out of a DPMS AR10 with a 28" Krieger in 6.5x47, I'm going to be doing some testing with these milder primers in the bolt rifles. However, I was loading Ramshot Hunter in those AR test loads; five will get you ten that RL17 will still perfer the 450s.
