Norma 6Dasher Brass

[dedeadeye]

Got Mine


Norma right, Lapua left


Ray, notice the slightly thicker rim. Some of
my older RCBS #3 shell holders would not accept the new Dasher Norma case. The Redding shell holder work fine. See you at the World Open. Roger

Got mine as well, looks great!! The first thing I like, is the 6 dasher head stamp.

First of my new cases trimmed to 1.555, neck turned to .0105, full length sizes and fired 3 times with 32.46 H4895. Case fell out of my Borden BRM.

The long neck is going to make H4350 work better . Larry

I have a "barely sufficient" supply of that too...

dedeadeye/Rodger,

Other than the length, does the brass fit your old Lapua chamber good, and any problem using your resizing dies?

Thanks

 

[DBLNUT]

What is the best reamer to use for this new longer 6 Dasher brass?

 

[rcw3]

Lot of people received shipments - but what's the measured OAL of the cases and what's a loaded neck dia?

 

[dedeadeye]

Brass fits my old chamber no problem from my Harrel fl bushing die. That load/lot of H4895 gives me 3060 +- 6 fps in my .237 Krieger so psi is about 63500. Flash holes are centered and round. The 10 cases that I am working with, flash holes all are chamfered. Necks walls are .0132-.0124
and turns very smoothly? Brass in early stages seem equal to or better then Lapua. Shooting them a 1000 yards will tell the tale. Roger

Roger

Thanks that will tell the story Larry

 

[22DASHER]

Somebody just take a case and firing it 10+ times to see how the primer pockets hold up.... That's the only info I need.... If that brings good news then I can make them work..

Roger,

That sounds great ! I am looking forward to receiving mine. Sounds like they will be a great option.

Just a heads up.

We have had a couple of calls where the cases were too tight in the rim/base area to fit into the standard shell holder.

1) We have spoken to Redding and they are making a special batch of No. 1 shell holders that are plus .004" in the slot and we should be getting them by the end of next week.
2) We have also ordered a special cutter (due to arrive tomorrow) and will program our CNC machine so we can skim off a few thou from the existing shell holders. That way we can satisfy some of the people that need them in a hurry in case these cases do not fit their shell holders. Those should be available for purchase by the end of the week.
