Stretched out the 28 Nosler

[Huntnful]

Decided to work up a load for some Berger 180 VLD Targets in my 28 Nosler recently. The gun is throated for 195's, so the 180's sit with the boat tail slightly up in the neck of the case. I went just below pressure, and ended up at 3130fps. These things freaking SHOOT.

Yesterday I went out to 1120 yards to verify the BC of the bullet. My first two shots were a little high and left of the plate. I came down 1 MOA and held 2 MOA of wind and then printed this consecutive 3 shot group of 6". With only 3" of vertical separation. Pretty happy about it!! I shot the group off of a bipod and rear bag out of the bed of my truck.

The verified BC of the bullet is .375 G7 instead of the factory stated .350 G7

Looking good, but one Q I have is how did you know what the pressure was?

Just standard pressure signs. Heavy bolt lift and ejector marks. I have neither. They start around 87gr. of powder

That's awesome! Looks like fun.

N570 is great powder

good shooting, is your barrel 24"? Surprised your at 86gr of n570 for 3123, In my 28N am using 82gr of n570 and getting 3130, same brass and primers, my barrel is 26". I am shooting at 6000ft.

It's a 26" barrel. I'm at sea level. But I do feel like all of my bullets take an few extra gr. of powder to get up to certain velocities.

Nicely done!

Who did you have do your chamber/195 extended throat?

This is exactly why people should not use other peoples " pet" loads.

 

[dogz]

different chambers, different clocks, different days to clock and so on...........

Exactly what L.Sherm said!

The most impressive thing about this thread was that OP had virgin ADG brass. @Huntnful what is your coal if you're .07 from the lands? Was that max length for reliable feeding or was it a result of load development?

On the other hand, as a word of caution, in my Browning max long range 28N using N570 in a Norma case and the same bullet seated to a coal of 3.395 I show pressure signs at 79 grains and at 81 grains I'm close to blowing out primers. So as great as the above results are (and they are and congrats) I don't suggest to people less experienced with a standard factory rifle start their hand loads at 84 grains and trying to duplicate these results.
