6 Dasher, Alpha Brass

UPS dropped my Alpha 6 Dasher brass off a bit ago. To say I am impressed with Alpha Munitions is an understatement. I got on the wait list for the brass about a month ago and was notified about two weeks ago as to availability. Ordering was easy and I got almost immediate confirmation. I got an email from Tom Danielson at Alpha with their specs on the brass as to tolerances for neck thickness, case weight variation and flash hole.
I weighed brass and it came in consistent, within .5 grain, compared to older gold box 6BR brass. measuring it, I came up with a .002 difference in brass. Brass length is 1.540 +/- .001.
I got an email telling me to go to the Alpha site and order the data card for my ammo boxes as well. Then, when I opened the shipping box today I found a hand written thank you.

I believe your brass length measurement is incorrect.

I am also on the waiting list and have heard nothing. Their website still shows as "out of stock." Huh!

Ditto. They're working hard to make this the go to brass. We'll see.

I tell ya what. I got mine today as well and it looks like some mighty fine consistent brass. I’m hoping to work up a load this weekend.... I’ll post results as soon as I can.
 
I'll shut down my snow blower for a bit to add some input.

First thing, my Alpha Dasher brass is from a preproduction run.
I'm pointing this out in case there were any tweaks made between the preproduction and the regular run.
The Alpha Dasher brass is some of the most consistently uniform brass that I've had my hands on.
Weighing 50 pieces resulted in an 0.8 gr. total weight variation.
Checking neck thickness runout reminded me of the first Lapua 6BR brass I'd ever handled with my dial indicator needle never moving more than .0005".
I prepped the Alpha brass to the same dimensions that my Lapua brass is currently being run at.
I clean the necks to .0127' and after firing with a moderate load, I trimmed to 1.550" length.
Worth noting is that when I turn my Lapua necks to .0127', I have about an 80% cleanup, with the Alpha, I had about a 95% cleanup. Did I say this brass is uniform!!!
I then took 15 Alpha and 15 Lapua cases, all fired in the same chamber but not resized and did a volume comparison with Accurate 2230 ball powder.
My findings as follows:
The Alpha Dasher brass weighed an average of 5.5 gr. heavier than my Lapua brown box brass. (Sorry, I don't have any Blue box Dasher brass to use for this comparison)
Alpha Dasher brass held an average of 1.1 gr. less ball powder than my Lapua brass.
This difference in volume required a reduction in the charge weight from my Lapua loads of 0.2 gr. with H4895 and CCI 400 to put me back in my tune window with the Alpha cases.

I used this combo in the Montana 1000 yard season championship in August for all of my targets on Saturday and managed to clinch Heavy Gun group agg for the day.

Since then I haven't had decent enough conditions to do any more testing.
Maybe in a few months!!!

Meanwhile, back to the snow blower.
 
I've been working on 500 Lapua pieces. Light 127.3 to 129.4 Heavy. Avg about 128.3gr. Right now a no turn Dasher sounds great.

A good solid post full of data and first hand experience. :) Thanks!

Just got UPS tracking notice saying mine will be delivered tomorrow.
Yes, I have a couple 6BRA barrels but the 6 Dasher is still serving well after a decade (off and on) of shooting them.
BTW, I don't think @birdog is ready to change the name of the famous Dasher Dome either. o_O

Although the "BRX DOME" or "X DOME" has a nice ring to it.
