6 Dasher thread

[KyleR1985]

I could be wrong, but I think the issue came from when folks were forming dasher brass.

Peterson and Alpha make dasher brass now. I’m pretty sure that brass will work with pretty much any reamer.

They both work in my chamber which was done by a PTG reamer with a .272” neck.

Yes it seemed issues came from forming brass, that was what I was reading as well.

I did a lot more digging last night before I read this post and came to the conclusion that the alpha reamer was the way to go.

A lot of guys reporting the reamer working well with other brass as well (Peterson/lapua) with no neck turning.

I would likley go all alpha and make life easy for myself.

Did you get .120 freebore reamer? I was on Mansons site last night just surfing options

I bought a .120 reamer made by alpha. 120 seems perfect for off the lands shooting of the Berger hybrids and 107tmk.

Yea you can use other brass in the alpha chamber too and vice versa.

Alpha is a .274 neck I believe. And has body and neck radiuses that are slight.

I’d avoid a .272 neck for alpha brass in a field rifle. Getting pretty tight

Thanks for laying all this stuff out, good point on the .274 neck. Those are the little details I would overlook.

My howa mini has a .275 neck now, because the arc chamber didn’t clean up fully. We used a chucking reamer to make the whole neck .275” instead of .272”.

If your doing a tikka I would just source a blank and send it to fisher t&c, he has done my last few barrel and iv been very happy with his work.

That was the plan, tikka. Thank you I’ll look him up

Oh man, I’ll be keeping an eye on this thread. I’m going to have a hell of a time deciding between the 6 Dasher, 6 GT, or 6 CM next year when I start a new build.

Any of the BR or BR-improved cartridges are an absolute blast to shoot with extreme accuracy, effortless load development, and minimal recoil. There’s good reasons they’re so utilized in the comp world. I do prefer something with a bit more juice for wind deflection if I’m hunting out to 500+ yards. In gusty conditions, a 105-110 grain bullet at 2800 fps is not ideal for first round impacts, in my opinion. But everyone who reloads should have one. I’d take a dasher over a 223 any day.

Game dasher. 1100 rounds into it, getting ready for the first match of the year.

The g2 recoil x….. wow. What a difference. It’s like shooting a brake again without the concussion.

Doing dasher things I see....when do you typically retire a barrel? I ask because I used to pull them at 1,100-1,200 and start on a new one. My fear was they would start opening up during a match and I just couldn't chance it.

I can’t stay but most seem to pull them at 2000 rounds in the prs world. I’d expect my hunting barrel to go even longer.

Iv got another match barrel chambered, just waiting on an action nitride from UM to screw it on and start breaking it in.

My goal is to have 2 barreled actions for comp use in rotation and 2 for hunting in rotation.

Curious where you draw the line for a gun for 500 yards in regards to wind number?

On paper it seems I need to jump significantly in powder or bullet weight to gain much at all. With the 107 and 116tmk now you’re looking at pretty efficient bullets going at a decent speed.
