6-6.5x47 Dasherized Imp.

[SHootSTraight22]

I know the name doesn't look all that pretty "6-6.5x47 Ackley Improved Lapua" but imagine the case.. The case would be identical to the 6mm Dasher just 0.297 longer.. Same neck/shoulder as the Dasher just extra powder space.. What you think?? Has anyone done one before? Maybe it would be worth trying with the 115gr DTAC's shooting beside the 105gr Dasher guys??

Re: 6-6.5x47 Ackley Improved Lapua???

I havent done 6x47L ackley, but what I have done is "dasherized" the 6x47L. Which is even more case capacity, but a shorter dasher neck. I originally did it with a 243ai reamer and just ran the reamer short about 160thou or so just to see if I liked it and if it would be less temperamental than the 6x47L.

I really liked it so I had JGS make a reamer. It is called the 6mm Vortex (JGS actually named it that on the print,not me,lol)

It is basically a long Dasher or a short 243ai. I just shortened up a 243ai sizing die and it works great. The case capacity is in between a 6xc and a 6creedmoor. So its a pretty good improvement over the 6x47L.

The reason I did it is because I had a theory that the case capacity is the what makes the 6x47 temperamental. So I figured if I got the capacity closer to 6 creedmoor, which is a very forgiving case to load for, and higher than the 6xc which is also pretty forgiving. I could see if my theory had any validity.

Whether that was the problem or not I dont know for sure, but I can say with out a doubt that this case is much more forgiving than the 6x47L. Honestly the fireform loads are more consistent than any of my 6x47L's ever were.


I know some people have had great luck with the 6x47L, but it seems to me that many more people do not.

Anyhow, hope that helps.

I have a reamer and 100 pieces of brass that I would sell. DG

6mm Long Dasher I believe its called. A buddy has one and it shoots well.

I believe the PTG reamer spec for the "long Dasher" is a simple Ackley improved 6x47 just as the OP described, but I could be wrong about that so dont hold me to it.

What are the specs for the reamer you want to sell? I may be interested.

Hi Scott, have you worked up any loads/chronograph with the 6mm Vortex yet? I would really be interested in hearing more about it. 8)

Yes, I have a few barrels and they all are a little different.

My 8tw likes 42gr of 4350 with 105hyb averaging 3140. Most the matches I shoot have a 3150 speed limit. Otherwise Im sure you could push them much faster. I've got them up to 3250 with H4350 without a stiff bolt lift or any other worrisome pressure signs. However, Im sure the pressure is up there at that point. The x47 case just hides it very well.

I have a 7.7tw that I shoot 115Dtacs in at 3040. They shot pretty well around 3100, but shot fantastic at 3040. Thats 41gr of H4350

My fireform load is 34.5gr of vgt with 107smk(velocity around 2800), but I throw that with a bone stock Dillon thrower on a 650. So it can range from 34-35gr,but it still shoots very, very well. It really surprised me how well it shot, even out to 700yds.

I do have this disclaimer. I highly recommend using a false shoulder and soft primers(ie-205's) when fireforming.I was not able to get enough neck tension to just jam the fire form loads which led to premature case stretch. I dont seem to get any case stretch when using the false shoulder. The other option would be COW. Personally Id rather practice while fireforming so I dont use the COW method.


Let me know if you have any questions.

Great thanks Scott!! I thought this would be good! It just makes scents! A neck a little over .200 long, 40 degree shoulder, body around 1.364 (not including rimm height) Does that sound about right.. 6-6.5x47 Ackley Improved or Dasher Long Rifle, or 6mm Vortex??? I got it " 6-6.5x47 Ackly. Dashtex Long!!! " Thanks... What's your freebore??

Re: 6-6.5x47 Ackley Dashtex Long

Hey, if any of us here are interested in this lets get a group buy together from JGS for the reamer and Whiddon for Hydro forming dies??? Interest??? But, also I'm kind of interested in trying this with a 6mm Creed.. The Creed version would have the capacity of a 243 Win but with a 40 degree shoulder and short neck... My luck the 105gr bullet wouldn't won't to use that extra 50fps the Creed case seems to get over the Lapua case... Plus the Lapua case will last forever!!

Re: 6-6.5x47 Ackley Dashtex Long

JGS emailed me today saying that someone was inquiring about the reamer/print and asked me if I was OK with releasing it to the public. Which I thought was pretty nice of them to check with me. I said absolutely. So you should be able to just call JGS and have a 6mm Vortex reamer made off the print.

Darn, somebody came on here and saw our conversation about it.. I'm going to inquire about the reamer specs and case dimensions and see if that's what I'm describing.. It should be just like the 6mm SMACK...

I was meaning to ask, "hows feeding with this cartridge while running it hard, in the action?" Does the 40 degree shoulder catch some or a lot or none at all??

Let me know if you have any questions.

I have no trouble reaching over 3100 with a Dasher and a 106 bullet in a 28" barrel and it shoots ok i guess if you 1/4 min. but dropping back to under 3066 it goes in a .1. I have a 6.5 x 47 imp. that is sized with a Dasher die with the hole opened to .301 and that is interesting with the 130 - 140 gr. bullets….. jim

It feeds very well. I run the bolt fairly quickly since every second counts in PRS matches.
I have the reamer print, but Ive never posted pics on here and I dont have a photo hosting account anywhere. Shoot me a PM with your phone number or email and I'll text or email it to you.

Jim,
Is your 6.5 just improved or "Dashered". Either way did you see any notable gain over the standard case?

You mentioned you running a 6.5x47 into a Dasher die, I was wondering if your case necks are also as short... I was thinking about this chambering as well after I have about 2,000 rds down my 6.5Lapua barrel.. I was going to cut an inch off the chamber and crown end and have everything reworked to study this cartridge (6.5x47 Improved or Dasherized) more fully.. I'm interested in shooting the little 6.5Lapua case in it's 2,900fps plus node with this higher up shoulder.. One maybe able to even get enough velocity with the 130 Hybrids "pointed" to outshoot the 140 at farther ranges.. I'll run it by Applied Ballistics and model it out...

Re: 6-6.5x47 Ackley Improved Lapua???

Yea, that reamer name is misleading.. What Scott has is what I was trying to describe a "longer dasher" meaning just like it short neck and all,, just tall as a 6.5Lapua case.. Anyone interested in the regular improved version their is a write up at the Bulletin heading above.. April 19 2015 is the date of the article at the "Daily Bulletin..."
