The Harrell's dies will work fine. However, the Whidden dies are much better finished inside and out and the decapping rod holder is better and the lock rings are better.
If you are considering a Dasher, think about the 6mm BRDX. I have one. Getting 3000 fps with 105s and I have more neck to work with than a Dasher or BRX. The major reamer makers offer 6mm BRDX reamers: JGS, Manson, and PT&G. Here are 6BRDX groups with rounds loaded on the Whidden Dies. Top 3-shot group is mid-zero. Bottom 5-shot group has four of five in a low zero.

At suggestion of Sam Hall, I just load about 25 thousandths past "first touch" measured with a Hornady tool, with a lot of neck tension. I use 29.0 grains of Varget with a 105gr bullet. This formed the shoulder about 95% and worked as well as a higher charge. Shoulder fully forms out on second firing at 32.3 grains. I have a .270 chamber and I turn about 2/3 of the original 6mmBR neck to 0.267 before fire-forming.

Tom,
Cases were trimmed .002-.003 before neck-turning (to even out the long ones). Blow length is very consistent at 1.545-1.546 after two firings. Jam and shoot. I have a couple shorter @ 1.542-3 but I think those were trimmed a bit short.

Paul,
I have found with any of the 6br improved cases that it takes two and sometime three firings to be fully blown out 100% I talked with you sometime back about F-F with cream of wheat and I was way over on recommended powder charge to get it blown all the way out,..you told me it was way too hard on the cases to hammer on them like that and it wasn't necessary they would finish out close enough on the second firing, I played around every way there is and I found you were right about stressing them to much on the first firing, I now just jam and shoot same basically as you and Tom are doing and that works the best for me. If I go with the DX this year I will jam and shoot it as well. Tom/Paul are you F-F with a designated F-F barrel or are you just using your good barrels?

Tom,
I have been using a ff barrel for the brx but I think I won't on my next build I agree the barrels need a few rounds through it anyway
Just got off the phone with Russ, I have two action on there way to Gilmore right now, getting excited, waiting for Kiff to call me back as we speak

GRRRR!!! dang it,..he did the same thing with both!! of my brx dies, the first one was okay because I didn't know but the second I stated I wanted it 1.550 and it came 1.570 and I can't even come close to blowing them that far! thank's for the reminder though I will be sure to really make that a point, I never noticed a bad carbon ring or anything but it was always on my mind!!

Tom,
I just got off the phone with Dave, ( he is always a pleasure to talk too ) anyway he said as far as the Dasher and BRX were probably getting Generic prints with our reamer because he finish the reamer at 1.555 +.05 for BR shooters and + .010 for varmint hunters for the blue box Lapua brass, that leave us about .010 clearance which is just about right, he was on the highway so I didn't order my new DX ream but he said he was making them and I am quoting him off memory so I hope I am not mistaking on any of this, but 1.550 on them because there a little shorter even yet,..He said someone had called and questioned about the long throats was that you? anyway have you actually measured your chamber length? sorry for asking I am sure you did but I am just curious? He also told me about a new cartridge he has been working on but I don't know if I should put it on the open forum, sounded like a true long Dasher from a creedemore case. later
