Looks good, that barrel looks like its 40" long in the second pic. LOL!! 26''? Im a fan of Picatinny mounts too and 6mm's. Let us know how it shoots.

I have one Dasher and am going to do another. My first has a .272 neck and .050 freebore. I just got another reamer, this one with a .269 neck and .090 freebore. IMO they have great potential as they dominate the winners circles in the mid-range BR game (600yds) and are reputedly quite capable at 1000yds.
Henry did a couple of builds on TC Icon actions for me, and they were decent shooters. The Icon platform is a great choice.
I did my fireforming using the stepped neck, and jambed 'em .010 to be on the safe side. Unfortunately, I got my first brass a bit stretched as I went a bit too hot with my fireforming loads...My second set of brass worked out fine using 29gr of Varget behind a SMK 107.
Nice looking rifle. You will love it.

Thanks guys i will definitely post some pics once i get it out to the range and do some load data. Barrel is 28 inches long. I think it looks longer because the gun originally had a 20 inch barrel so the forend of the stock is a bit shorter than normal

looks great , balance looks good for the pod, lee

Don't be surprised when your 10 shot break-in groups with fireforming loads all go under 1/2" at 100M Have you tried the feed from the magazine..as I am wondering about how the short case navigates forward from the single stack? Not having to tinker would be a bonus.

Took some more pics and added a scope. Just a comparison of the 338 lapua and the 6mm BR soon to be a dasher.

Are you using a hard jamb to control headsapce during fireforming - can't see the neck detail? Here is how mine look.
Left - parent 6BR
Second left - necked up with .257 button
Third left - top half necked back down to 6mm to create false shoulder
Right - After fireformed in dasher chamber

Im gonna be using a hard jam to fireform. I can't believe that little case will spit out 105gr bergers at 3000 fps its amazing

[260 Rem]

The 6BR case has got to be one of the more efficient cases. Neck it up to .30 cal (30BR) and it can launch a 115gr at 3000fps. Here is my 6BR family picture.
Left - 6BR parent
Center - 6 Dasher
Right - 30BR

Nice that 30br is something else
