300 Norma Improved 35 degree

[Alex Wheeler]

Ya, Id say those Atips did very well. Definitely a lot of potential. And they matched the 338 Lapua Improved's ballistics almost exactly.

 

[DangerRanger]

230 or 250 atip?

Heather is rocking it. Shot with her at Rattlesnake a couple of times. That girl can shoot.

These are the high node and low node in Alex's chamber. The small one is a 210 berger with 83.5 grains of h1000 at 3050fps. The high node dropped one out, but it was a 210 berger with 89.0 grains of h1000 at 3260fps.

Here is a 245gr berger group from last week. This is n570. This charge and bullet have repeated as well.

Thats in a 30" rock creek if I remember right?

Correct. It has shot several bullets and powders well.

 

[284winner]

Excellent with 245s.

 

[GlennK]

Repeat testing with 210 vld at 1000yd. Used a 1/2 grain more of h1000 to see if it helped with shots dropping out. Looks good so going to try other bullets to build a data base

Hi Everyone- I'd like to build a 300 Norma Improved on my Desert Tech with this 35* shoulder. Where can I find a reamer print or rental, and where is the place to order dies from?

Thanks

Does anyone have AMP settings for this cartridge. I have Nomra brass fire formed.

@GlennK should have it, but for Lapua brass.

I have Aztec settings. If you want to send me a piece of brass, I could run it and then you could get the conversion from amp.

Glenn, which pilot are using?

 

[Rem06]

tag, this is one impressive cartridge, kinda of like the 6.5x47 when it came out! it wont go away anytime soon!

My 300NM just loved the 230 and H1000 for accuracy, and i tried passed on RL33, and Retumbo. N570 was out of my budget

 

[Alex Wheeler]

Ya, H1000 is still my favorite in this case if the barrel likes it.

 

[Rem06]

i would stay with it

of coutse you would have to do a bourbon run to Fort Knox to get it.
