Create a channel Learn moreIt all depends on who you get your hydro-form brass from. See my recommendation above. The only place I've gotten true "load-and-shoot" brass.So concencous is after you get hydrocormed brass back you should full length size it before fire forming? Or do people just clean brass then load and finish fire forming the. Resize after that?
Thank you chad

I would do a good job of sorting those blemished bullets. I have found they are in terrific condition, but they seem to come from many different lots and/or dies. Therefore lengths, base to ogive and weights vary. Because of this I’ve played hell with consistent seating depths. I gave up for now and will shoot Berger’s in my BR and use the blems for fire forming Dasher brass when I get one. I’ve had good luck with first run RDFs in 6.5 for steel banging.

I believe the Hodgdon reloading page lists 6 Dasher load data.Does anyone have a load with 4166 and 105 hybrids
Yep it's on there but no 4166 with 105 or 107I believe the Hodgdon reloading page lists 6 Dasher load data.
It is just a tad faster than Varget.Yep it's on there but no 4166 with 105 or 107

I tried BR-4's, but would get a few hang fires in cold weather.
Going to give the 110's a try this week. This is my first Dasher barrel only 60 rds fired so far, I'm a 6.5 and 6 Creed guy.
Loving the Dasher so far.
Do you think if I took varget load for br and dashed and got the diff and backed off a few 10ths would that be a starting point for 4166 I also wanna try VVIt is just a tad faster than Varget.
Start with Varget loads and I have ended up with higher charge weights than Varget.
Enter at your own risk.
Every rifle is different.
YMMV.
Yada yada.
I did load 110 SMK over 33 gr. of 4166 and got 2880 fps.
My 105 Hornady loading is not getting posted for the above reasons.
In my BR 29.9 grains if 4166 and 30.0 grains of Varget are the same speed for all intents and purposes when it’s warm. Varget is slightly faster when it’s cold out.Do you think if I took varget load for br and dashed and got the diff and backed off a few 10ths would that be a starting point for 4166 I also wanna try VV
Triggs75, I just tumbled it to clean off some lube and fired it. It shot great the way it came, ready to load and go!
You could have a bunch of different lots of brass that way. It would be hard to nail down tuning issues since likely you will have different case capacities and neck thicknesses.Same for me. Makes it easy. It's nice to have a few buddies spotting brass at matches to find 95-99% of your $1.55 brass.
What 4166 load did you start withI may end up buying hydroformed brass someday, but had to try forming my own first... just because.
Getting the hydro die and consistent technique down took a dozen or so cases, but I've got it figured out now and am actually quite pleased with how uniform the cases are turning out. See attached picture with new 6BR case on left, then case out of hydroform die, case after full length sizer die, and finally once-fired case.
I got to the range to try out some initial load work ups with H4350, Varget and IMR 4166.
H4350 grouped pretty tight across more than a 2 grain spread, but not sure if I'm willing to use a drop tube that seemingly would need to be almost ceiling high to get enough powder in to get the velocity I'm looking for. (knew this but wanted to see because I have a lot of this powder)
Varget seemed okay, but need to load more cases to get a little faster than my loads were today.
IMR 4166 was the standout in what I tested on this trip. Look to have a nice accuracy node right around 3000 fps. No pressure signs yet so will keep going up a little more to see what happens.
After this first range trip, already thinking I'm going to end up really liking this dasher thing!!
What 4166 load did you start with
Do you know what you where getting around 32.5I started with 31.5gr of IMR 4166 in my hydroformed cases. I only loaded test rounds up to 33gr which were right around 3000 fps with no pressure signs.

I appreciate the infoI was getting around 2950 with 32.5gr of 4166. All testing was with the 105gr RDF's about .010 into the lands.
Brass: Best I have used is from DJ's Brass Service. Shoulders are sharp and length is consistent. Brass is worked hard during the hydro-form process and his is annealed after. Best of all it shoots well right out of the gate (reduce load slightly first firing).Going to take the plunge and get a Dasher spun up. Just wanting to see if I am on the write path for collecting components and tools:
Brass: purchasing hydroformed Lapua brass from @Rimfiremike
Powder: Have a lead on a couple kegs of Varget
Bullets: Going to run 110SMKs has I have several thousand, could be talked into 108ELDMs if performance will be much better
Primers: Planning to use CCI 450s but also have BR4s as well.
As far as dies, is there a consensus on the best out there? I have Whidden and Redding and like them both, need micrometer seater die and would like a bushing full length die.
What bushing will I need with the lapua brass?
Any other tips or tricks would be appreciated!

Powder: you're right on that choice for sure. Varget is the best I've used and I've shot thousands of 6 Dasher rounds.
Bullets: If your twist is right for the 110 SMK then that is a great choice. The "new" SMK's are very good quality bullets.
Primers: I would stay with the plan to use CCI450.
Dies: Mine are Whidden and have not regretted using them over Redding. My loaded round runout, using Whidden dies on the Coax, is never more than .015 total.
I do have a couple boxes of the 110SMK but yet to shoot any. I was merely stating that the newer SMK is a much better (more consistent) bullet than before they started pointing them at the factory. I really don't think the overall shape is any different than it was and I have always found SMKs to be very tolerant of seating depth.How sensitive to seating depth are the 110gr smk? Reason I ask is with 105 hybrids I can run from. 020 to 060 off the lands with no change in accuracy or velocity. I heard the 110gr smk can be touchy and requires a lot of adjustment as the barrel wears.

Here at my 450' ASL I felt like it would take a 7 twist to fully stabilize the 110 past 800 yards or so and have just had a 7T Hawkhill barrel done in Dasher.
Like you, I keep the Hybrid well off the lands. Also like you I find them not to require as much "chasing" as the barrel wears.
I would venture a guess that you would be. The 7.5 might do it here during summer but I doubt it during cooler temps.I am at 2500 ASL, hopefully the 7.5 will be enough.

Jumping aboard the Dasher train (choo choo) this year and I thought I'd share my findings so far with you all:
Gun Specs
- Defiance Deviant Elite LH
- International Barrels M24 contour, 26" long
- MDT Elite Brake 3/4-24
So far I have done 350 ish rounds of FF-ing with 90-105 gr bullets, jammed 0.030", 30 gr +/- 0.3 gr of Varget, then I started load dev.
I have run the 105 Nosler RDF's at 0.040" off the lands (the 1.735" is CBTO with a custom gauge):
View attachment 7031927
The 108 ELD-M's 0.020" off the lands:
View attachment 7031930
The 32.4 gr load was highlighted because that was what I ran at a club match last weekend, but more on that later.
However, since running those two ladders, it appears that my barrel has further sped up another 50-75 ft/s as these are the numbers I got yesterday!
105 gr RDF:

and 110 SMK:
View attachment 7031944
I hope this proves useful for anyone out there It looks like I will be running the 108's this season, as 105 Hybrids and the 110 SMK's are hard to find/expensive up here!
What kinds of speeds were you getting with the 112s in a BR? Barrel length? What is the BTO of the 112s?My dasher barrel will be here tomorrow.
27” HH
.150 Freebore
7 twist m24 contour
Brass from @Rimfiremike
I’ve got 105s and 112s on hand. But will be focusing on the 112s as they have shot great in my 6BR.
I’ve got RL16, H4895, 4166 and varget on hand. Lots of H4895 so I am hoping to use that. From what I’m reading H4895 may be a bit fast for the 112. Didn’t have an issue in 6BR though.
What kinds of speeds were you getting with the 112s in a BR? Barrel length? What is the BTO of the 112s?
Sorry, I mean the base to ogive of the bullet itself.2760 is where the node has been. H4895 29.1gr. BTO is 1.805 with a 30thou jump. my BR has a .120 Freebore
26” HH 7 twist
Sorry, I mean the base to ogive of the bullet itself.
Ah, I got you. .697
What free bore is your barrel? That is a wide range of bullets with very different base to ogive distances.
