Gonna go for a new Dasher build - some questions please

[dkhunt14]

Why not just get the Wilson micrometer seater that is already configured for the 6 Dasher?

Fit of case for bullet alignment. I also like the stainless version because it doesn't rust and comes with a micrometer top. The Arbor press dies give great alignment and you can feel the bullet seating better. It is more money but I feel is worth it. All you got to do is run your reamer in and you have an exact fit of your chamber. With the 6 BR one you only remove a little material. Matt

Would you consider Harrels FL die, that they match to your cartridge a better choice than one of the off the self brands like a redding/forster,

Yes, because it is made to a match......
If Whidden offers the same, then Yes. If not, then No.

A good example:
A new guy to a 6Dasher a few years back was having issues with a "click on top"
He was complaining and blamed that the reamer mfg. was making reamers to small.
In reality, the problem was, the "off the shelf" die mfg. was making the dies to big.
He had reamers ground until ended up with a good match up to his dies.
But if he would have had dies made to match from the start, he would have never had any issue, and been money, time, and agony ahead.

If you haven't ordered the barrel yet, I would suggest faster then 8-twist, in the 7.8 to 7.5-twist range.

hmm, I wonder if that's why I can't get the JLK's to shoot as good as the Berger 108's in my 1-8 twist , mind you I've only shot them at 100 so far. the 108's will bug hole over a wide seating and charge range where the JLK's won't group as tight.

Would the Redding Competition Micrometer Seating die if purchased in 6BR and then reamed with my 6Dasher reamer work as well as the Wilson? It would save buying an arbor press.

That is good way.....
And is what I use myself for most. I do the same to the sleeves of the Comp Neck Die's as well.

You are doing better than me i could never get the 108 to shoot that good, i now use them to fire form but…. DTAC115, Spencer 103 and the BIB 104 work ok for me and i will include the Berger 105 VLD to that bunch also ……… jim

Don't start cutting corners, You can not feel or put numbers to the seating force with out the arbor press. That will cause vertical, i've used a drill press in a pinch………. jim

Generic fit verses a custom fit..... is my input.
With improvement to runout and seating consistency being my reason.

"Off the shelf/generic fit" dies are not for me with my custom built rifles. I want EXACT and determined fits for minimal sizing, concentricty, and seating gains. To much is left on the table in many circumstances by going the cheaper and/or readily available routes with generic fits - IMO

Seen it a few times, where someone has spent $$$$.$$ on a custom built rifle, and give up small portions of accuracy by not getting the most out of there brass and loaded rounds, because they take the dies for granted.

My 2-Cents

Donovan and Jim,

Would you consider Harrels FL die, that they match to your cartridge a better choice than one of the off the self brands like a redding/forster, Are whidden dies close to custom?

You send fired cases in to Harrell's and the will send you the die they recommend, if you don't like what it's doing call and they will either make you an other to what you want……. jim

Ha I was using the 108's for ffing, maybe I'll switch and us the JLK's.
I checked out Jlk's site, They say optimum twist is 1-9 for the 105's , BiB's says 1-8.3 for the 104's . can't find anything on the DTAC or Spencer. so are we spinning them to fast ? BiB says nothing faster that 1-8 twist.

6mmcidasher, My post are not from a book or what i read…….. i shoot the BIB 104 in tiny groups of less than a .1 with a 7.83 twist so don't shoot it, if that is what you read... Get the point, but i can use and will use a 8 twist barrel because it also works the same. It will save the the 7.83 barrels for VLD's that shoot better in the faster twist. I'm looking for the factors that help put a bullet asleep, they are not affected by the wind as ones that aren't…… I'm more concerned about small groups at 1000…….. jim

Something not to be overlooked when using your own chamber reamer for your seating die is that you have a perfect chamber gauge.

Just finished re-barreling my Rem 700 in Eleseo R5 with new Krieger 7.5" TW Palma contour cut to 30". PTG reamer for .266 neck, .135'FB and using Berger 108. Only have about 54 down the tube for powder test but it is beginning to shoot. Barrel replaces a similar one with 8"TW. Don't see any issues yet with faster TW.
Did several other barrels for my son with same reamer for Barnard and Panda F class actions and will see how they work.
