6 Dasher, Alpha Brass

600 yards, believe Alpha brass is going to work out just fine!

Can you provide any information on how you had to modify your normal load to work with this brass, it any?

It is a new barrel, so complete load work-up.
However, it is right in line with what I would expected with BR brass once fire-formed.

Is it correct to say the Alpha 6 Dasher brass is the same overall dimensions as the Lapua fireformed brass (unlike the longer Norma brass)? I am planning a 6 Dasher build and need chamber it correctly.

Yes, As near as I can tell.
I shoot them in my Lapua chamber, so far I’ve had very good results.

I realize that most shooters fireform. I just would prefer to buy new and spend more time learning to shoot better and get a good load worked up.

kind of excited to build a new rifle and shoot this caliber.

thanks

I wouldn't expect the same results from new cases until there 2nd firing, without having to tweak the load some.
Differences in case capacity and case hardness from new to ounce-fired being the primary reasons why.

Oh for sure. I was referring to fireforming from 6 BR Lapua cases as opposed to buying the Alpha Dasher cases. I am 1hr each way to the range and I really can only go once a week.

Thanks much

The groups above in post 142 were shot with virgin brass.
Based on my limited experience with Alpha Dasher brass, it compliments the Dasher nicely.

I will start with getting some when my name comes up on the wait list.

Meanwhile I will be looking to find a bullet and get the dies.

Nice this is American brass.

I shot two ladder tests with Re-15 yesterday. I went up to a squeak over 3100 on virgin brass. Just popped the primers out and inserted new primers. I could not notice any difference in force between taking the primers out of the first case (lower end) and last case (higher end) brass.
Primer pockets were good and tight on the high charge/vel cases.
It is kinda sweet to have good brass that will shoot right out of the box.

My wind reading skills need some work, but I think the Alpha Dasher brass is up to the task.
600 yards


Turned the necks, load and shoot.

Assuming you didn't throw away the tooling to make the smaller diameter flash holes. I still have one of the best dasher barrels I've ever seen laying here, and enough powder primers and bullets it was on. I would pay the going rate for some of each, and test this out at distance if you'd like. If there's something to be gained I'm cool with putting in some effort on my end.

Tom,
did they take you up on your offer?

No, but I have plenty of time on my hands now....A lot more so than when I offered lol.

So far what I've loaded in this brass is within about 10fps with same powder charge as Lapua. I do like to run a smaller load through first loading to try to "work harden" the primer pockets. I think the fireforming of Lapua accomplishes this in the steps needed to make it. I don't know if I'm right or not, but it makes me feel good.

Just weight sorted a new batch of Alpha Dasher brass
Yellow are the 5 lightest cases
Red are the 5 heaviest cases
Shot at 600 yards

I'll take your light ones since clearly the rifle likes the heavy ones better .

On a serious note. Do you find you're backing off powder as compared to lapua cases?

It is to close to call.
My testing indicates I have to adjust H4895 and RL-15 for each match. I have one rifle shooting Alpha and one Lapua, both cases are so close in charge, I cannot say it is case volume. If there is a difference, it is mighty small and within the spread I would expect to adjust on a normal basis.

FYI this is a new, as in brand new HV Krieger I am breaking in. Trying to sweet-talk the green rifle into making weight to shoot her in LG. My oldest daughter commandeered my LG and kicked my but with it!

I have been shooting some smaller contours on purpose, heavy Palma will handle heavy gun groups just fine with the 6mm stuff. There's probably a heavy Palma in my pile down at Alex's if you want to try that route to thin her down.

Do you happen to know if both Alpha brass in 6 Dasher and 6 GT have .080" flash holes or 0.59"?. I looked on their website and I couldn't find any info, other than small primer.
