20/22 NOSLER

[searcher]

Has anyone tried this in either an A/R or bolt gun?

I AM NOT RESPONSIBLE FOR ANYONE SHOOTING ANY OF THESE LOADS IN THEIR OWN GUN.

My brothers Proof research carbon fiber 22in AR-15
Around 60 degrees outside when tested

Factory loaded 62 hp varmeggeddon was around 3000 and 55 gr ballistic tips were around 3200. I do not remember exact numbers

New nosler brass, H4895, 53gr varmeggeddon, BR4

22 nosler Velocity
53 grn/29grn powder
3311,3288,3314,3343

---THIS IS MAX POWDER CHARGE THAT NOSLER LISTS---
30 grn powder/ one hole group -- This is his load
3434,3410,3450,3422,3490

31grn powder
3643,3642, 3693,3638 - showing pressure signs

32 grn powder
3756,3738, - stopped shooting was massively over pressure

Also tried varget but it was impossible to get those kinds of speeds

Do you always go up 1 grain at a time when doing load development?

You could probably load up .2 at a time between 30-31 and find something that’s fast a little more repeatable

When working with a powder charge that small a .2 change in charge weight can be significant to accuracy and be a little safer to develop

Sorry for veering off OP...

No.... varmintexpress or I don’t have any experience with a 20 Nosler hahaha

It is a 22 nosler

No not usually.

Also why I made it very clear to nosler's listed max load. Just needed some speed and accuracy to coyote hunt with. Just lucked up with what happened in the results

I know.... the OP asked about a
.20-22 Nosler.... (now it’s proper)

 

[Ncvarmintexpress]

I know.... the OP asked about a 20 Nosler....

With the "/" in the title and "either" in the original post I thought it was a question of either chambering.

OP was asking about necking down.

He actually wasn't talking about a 20 nosler either, they're two complete different chanberings. The brass casing will have different shoulders.

I called it a 20 Nosler.... knowing he was talking about necking down.

The either is referring to an AR or bolt gun.

Not either chambering.

I believe he is looking for load data on a .20-22 Nosler.

Which neither of us have.

Yes - I'm all dialed in with .22 Nosler loads. I'm looking for someone who has necked it down to .20 caliber.
