30 Nosler

I’m sure it would work but I would try n570 ,n568 or retumbo if you have any of them I have no experience with 20N29 I just know it’s a slow burner.
My buddy is using retumbo in his 30 nosler with 245 gr Berger’s and it works great.
 
Thank you , I can find N570 but no retumbo. I know its slow, but I was hoping that the length of my barrel and 1-8 twist could help. But Im not sure

I’d give it a try first.
Here’s Berger’s load data
