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
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
With the "/" in the title and "either" in the original post I thought it was a question of either chambering.I know.... the OP asked about a 20 Nosler....

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.
