Norma 6Dasher Brass

[rcw3]

I have seen some wild number thrown around here but .008 loaded round clearance on a 6mm. is totally ridiculous……. James O'Hara

I think you misread my posting - - I said "Palma chambers" (i.e. as in .308"). The point was that people get "anal" about .001" or .002" additional neck clearance as if it's a huge deal when for some of us mere "no neck turn" mortal shooters it means nothing.

I certainly won't argue with you that Shiraz pulled off a big one here - - great job Shiraz, best wishes for success and prosperity in this venture! I was also making the point that for brass sales (which I would assume is one of the reasons Shiraz went into this - not just for bragging rights) hitting the "load it and shoot it" market is probably a good place to be as well. Not everyone likes to neck turn or trim brass - - in fact most of the shooters I deal with (i.e. I am in "the business" as well) don't like to do it at all and want to spend more time at the range and less messing with brass, loading, etc.. KISS principle works best for sales IMO.

I load for accuracy gains (as much as possible).. Dasher doesn't strike me as a cartridge for plinking, but I have been wrong before (many times).. If I'm gonna buy reamers and chamber in an inherently accurate cartridge I almost feel obligated to do it as to get as much accuracy as possible... I could just crimp my brass..LOL

Received the new Norma Dasher brass this afternoon. Checked the measurements
and got out my trimmer My chamber measures to 1.568, so trimmed five to 1.560
will load those five and see what happens.

Bullets.com now has reamers (limited supply) to first come first serve.
Print shows .104 throat which to me, seems way to short. With new bullets
having to be jumped .020 -.030 the .104 throat will be pushing the base of the
bullet way into or below the shoulder, but who knows with the longer neck
(if you use the new reamer) it might be ok.

What say you guys???

I believe the .104 freebore is a typical figure used for the traditional Dasher reamer. My current Dasher build will have a .104 freebore and that's what multiple gunsmiths I talked to use. I know some of the benchrest guys here will go longer, up to .130 or even .150. This is on the "old" Dasher before Norma brass.

With the new Norma Brass Dasher reamer and the longer case neck (~0.05" longer), I would assume that your seating will be fine in relation to the shoulder since the freebore extends that much farther away from the neck shoulder junction.

That number is dependent on the case chamber length. A .104 FB on a 1.570" chamber will be different from lets say a 1.555 chamber...

I think it's great you like to go "all out" for accuracy - - that's awesome - - accurate rifles and set ups are totally where it's at - - but in your posting it almost sounds like it's either "plinking" or "as much as possible" accuracy with little in between. We have done a lot with serious varmint hunters that, for example, might want to take 1000 rounds on a trip out to hunt prairie dogs out West but aren't going to slug through neck turning and trimming 1000 pieces of brass. Are they "plinkers" - - naturally not, but yet to dust off prairie dogs at long yardages they want something that delivers great accuracy in an "easy to do" package. There are also a lot of serious target, prone and other shooters that are serious about having an accurate bolt gun rig and an accurate cartridge and set up, but just don't have the time or inclination to trim and neck turn and they are far from what one might call "plinkers". Just a different perspective here - - not saying anyone is wrong in their thinking.

BTW - I don't think any of us would disagree that the Dasher has an awesome inherent accuracy pedigree - Shiraz scoped that one out up front!

To add to what Robert said, I think the market for this brass is going go WAY beyond Benchrest shooters. I personally know of at least three PRS shooters who are waiting for me to get my brass and reamer. They will likely spin up at least one barrel to try. I shoot mostly prone. I load for me and my daughter. Prepping 400 cases for a weekend when you work 60 hours a week before taking care of household responsibilities just doesn't do it for me. An extra .002" clearance and a K&M mandrel or a floating expander button does wonders for those of us who can live with groups at or just under half moa. Saves hours.

Shiraz has done us all a solid here. My groussing about the reamer doesn't have anything to do with him, it's just personal preference. If Shiraz didn't make this happen I would be looking at a 6CM, which I was hesitant to do after locking a 6.5x284 shut with a soft POS piece of Hornaday brass some years back. I am really happy to have Norma brass specifically because it's going to save me prep time and likely last longer.

Here's a "load it and shoot it" reamer design for the new Norma brass - - I realize some of the shooters might debate it's dimensions - - but for most of those we work with this will be perfect - - no muss - - no fuss - - no trimming - - no neck turning - - just load em up and shoot and have accurate fun!

Robert, can't see the image you posted.

My Hat is off to (SHIRAZ)
Not only has he done his homework.
He has invested in excess $ 500,000
Without him we wouldn't have Dasher Brass
Thanks Larry

Well I hope his investment is a positive for the folks wanting dasher brass when I see positive results I will bye some.

Has anyone addressed the rebated flash hole on the inside of the case?
I`ve not inspected Norma brass in the past, but it looks odd that these are drilled out in the inside to deburr the flash hole.

I agree, this is gonna bring the Dasher main stream I'm sure.. Well, maybe as main stream as custom chambers can get ya.. I personally don't load for economic purposes, the Dasher just seems to me like a PPC or something mainly competition oriented..

I bet a lot of varminter's turn and trim, who doesn't trim?

I prefer a .140 freebore in a 1.560" chamber. That would be the same as a .100 in a 1.600 chamber, so I'd say the .104" is perfect. The .104" is too short for a standard dasher reamer. The reamer Bullets.com has will be a good no-turn reamer.

Robert -
Is that a direct reamer print from JGS for the Norma Dasher brass?
Or is it your own edited version using a JGS print?

 

[johara1]

Robert, according to your post before on neck clearance, you said .005 was good for your no turn neck. So to be safe? so lets add them up a Bergers hybrid i have is .244 + .026 + .005 = .275 neck. So your print is wrong? you have an other mistake you can't push fat bullets out of a .2435 free bore diameter with out an accuracy loss. No turn is great,i guess but you have erratic neck tension and that is vertical at long range and with the excessive clearance you like case life is shortened and starting bullets out of center doesn't do a lot for accuracy. The .4714 is kind of max. kind of big for Norma maybe.
Your view is from XTC. and gas gun side where you throw them on the ground, mine is trying to get very bit of accuracy out of them. The difference is after i go to all the work getting them ready, i want them to last. A dent on the case mouth, it's done as a record round and with an AR that would about every one……..

I cant believe that all theses shooters have the new brass and all they have done is take pictures..!!!,,,,take some time away from photography and do a little loading,,,,,show us some targets and load data rather than glistening snapshots,,,I admit I have it made with my own shooting range just out the front door,,,,Roger

Robert Whitley is not just another poster here. I don't have any connection with him except for being EXTREMELY happy with my BRX & 6XCII reamers that he designed, made by JGS. Use with confidence!

As an aside to the main topic, if you want Quickload data buy Quickload! If you want to know the exact measurements of the Norma dasher brass or how it performs, BUY SOME - measure and shoot away!
