How accurate is your 6 dasher ?

[Frankr]

I got my first 6 Dasher built. fireformed some cases. found the neck were alittle too thick, not enough neck clearance. I have never loaded a 6 Dasher on a 6 Dasher die. I just got a Harrell's FL die and have not used it yet. well I sonic cleaned my dasher cases that needed the necks turned. I annealed the cases. I pushed a neck bushing down on the neck till it was jammed hard against the shoulder(lubed up good of course) pulled it off with a pair of channel locks, was very difficault to do, I bent some of the necks doing it. you could see the neck was bent. ran the cases on my expander iron. it seemed to straighten them out. I was able to turn them and get a good reading on a ball mic. But still may have some slightly bent necks. so I know I need to fire them so I can get my die set up. So I load 33.0 gr RL15 and seat a 105 berger VLD .020 in from touching using a 6BR redding comp/seater die cause I do not have a dasher seater die. I have no idea how they will shoot,i don't really care just want to fire them once to verifiy I have the process down that I am going to use to do the rest of my cases that need done. I went to the range to shoot some ppc cases that needed fired once also. I was going to shoot the ppc and I would have my pal who has a good delivery shoot the dasher cases for me. the conditions were gal force winds. I had flags set up to see in my scope. my buddy did not. the wind was the worst I have ever shot in. it was kind of a waste of time. but the cases needed shot. so we would give it our best. my ppc did poorly mostly due to new barrel,preloaded just to shoot the cases.so I could have them for another barrel. I used flags the best I could.my buddy shot the dasher with no concern for the wind. it was bad enough to blow a hat off your head some gust almost blew a tool box off the bench. the bullet hole by the #5 was a extra case. he did not want to shoot it at his group so it just shot it at the #5.. I was impressed how well it shot in those conditions, know the cases were not loaded as good as we know accurate rounds are loaded. im kind of thinking..i had to weigh that rifle when I got home 13.1 Lbs..oh yea it could make HV weight. could the 6 Dasher out shoot the 6ppc in HV under tough conditions..I think so at this point. I wonder how accurate it can get once I get it sorted out and tuned up. zero's
Oh plus it only has a 18 power hunting scope on it and it is real hard because the thickness of the crosshair cover the bull. he even said he had a tough time with that. he also said he feels he lost a shot or two do to gun handeling.all are 5 shots at 100yrds

I found the same thing as you when I switched from a Br to a Dasher. This case seems remarkably easy to load for, even more so than the plain BR. My first Dasher has only produced one group over 1/2" and that was fired by someone who had a little trouble feeling the 2 oz jewell
I'm going to have to start doing my load development at 200 yds because I can't split the hairs well enough at 100 to learn much.
33.0 seems like a pretty stout fire forming load.

I think you will enjoy the 6 Dasher and expect as good of accuracy as you would with a 6 BR . Actually I find my Dashers easier to tune than my 6 BR barrels . 33.0 grs of RL-15 is a lot for a fireform load . You will get much better case life if you fireform the Dasher with a medium 6 BR load. Load just enough to form the shoulders 95% and your brass will last longer than whacking it so hard the first time . FWIW.

Before you begin work on forming Dasher cases from 6BR: expand the necks, then turn all of them down to about .002-.004" on a loaded round, below chamber neck diameter. They will not be tight. Create a false shoulder before you fire form em. And for gawds sake, spend the money for Dasher dies.


Mine likes 33.4 grs. H4895, with 105 gr. bullets.

Tenring,
is there a better dasher die than a harrel's
Darrell

p.s. he said he got a harrel's fl die he just hasn't used it yet

No the dasher cases were not fireform loads. they were cases that had been fireformed. shot two or three times and I did not have enough neck clearance. new blue box brass. .2704 neck dia. I had a full formed dasher case that had been fired once to three times. that now needed to be neck turned. that's why I annealed then pushed a neck bushing down to the shoulder so I could get a good fit on my expander iron so I could get a good turn. I did my neck came out good. loaded round of .268 now. they were .2695-.270. so looks like I got a lot of thick necks.
but still they were not a good tuned load, on straight cases ect. and they shot extremely well in so bad,very bad conditions. I got a match report from a guy who told me the wind was so bad sunday they cancelled the 200yrd match. yea that is what we were shooting in. but the dasher just pounded them with no concern for it. I was very impressed..it shot that well in the wind. them 105VLD's buck the wind beter than anything I am used to shooting at 100yrds. I really did not think it would be that much of a difference. as I have allways favored a 65gr at 3,500+FPS and have shown a few people how well they work.

One hole at 1000 yards!!!!! No BS!!!


Of course, I fire the second shot and ruin it!!! ;D ;D ;D :'(

My best so far, 5 shots at 600 yards, 2.292, four of them in 1.343. 105 Amax, 33 gr Rl15, 450's. Savage 12ftr, with Rock Creek 1-8, 5R, 31" long, Weaver T36. Barlow

Try Berger 105 hybrids, jumped .015 to .020 thous, 33grs of varget. Will produce 1-2" at 600 if your gun is solid and you do your part.

I've tried the Dasher at the 100/200 game....over the long run, the 6ppc will out do it...the extra 3 grs of powder produces enough extra recoil that its just hard to be competitive against the ppc. I just I should add that I've shoot out 5 or 6 Dasher barrels over the past 5 years, so I'm pretty familiar with it. With that being said, it's quite common to shoot 5 shot groups in the teens while fire forming. My best groups ever, a .089, I shoot while if reforming brass. My best group at 600 is a 1.15" and 3.72" at 1000...If its not shooting 1/2 to 3/4 inch groups at 300 yards on a day with good conditions, your load is wrong.

Use 32-32.5 for forming loads...these loads will blow the cases out pretty consistent on the first firing. 33 is a little stiff..you might pierce some primers..

Your going to love this round!

Is Varget the powder of choice for the 6mm dasher?

 

[falconpilot]

Varget is more resistance to temp changes...burns cleaner as well, but is just a little hotter(pressures up higher) than RL15...I love RL15, but it gets dirter than hell, especially when shooting F-Class, 60-100 rounds a day..I've had great results with both! RL15 has been used to set alot of records in IBS 600/1000yards..
