Overall length is what really matters. How much of the bullet is into the case. N570 will be pretty slow powder for 196's. I ran H1000 with 215's and was in the mid 80's. If your throated long for the bullet, I would start at 84 and go up. I shot 84-85 with H1000 and 215's. N570 is about 2 grains slower.
So your thinking h1000 would be better powder. Was using retumbo. But can't find it. And everyone is saying n570 is better

I don't have Hammer bullets in my software so I used a 196gr bullet that probably doesn't have the same shank length which means that some of the data will be slightly different due to frictional forces being different. I've posted what I would consider the maximums, based on the estimated chamber pressure, for N570, N560, and Retumbo.
N570 approx 89 grains for a chamber pressure of 64,000 PSI (compressed load)
N560 approx 79 grains for a chamber pressure of 64,000 PSI
Retumbo approx 87.8 grains for a chamber pressure of 64,000 PSI
Personally I like the looks of N560 the best. I'd start with about 73 grains of N560 and work my way up. N560 looks like you can get good accuracy along with low extreme spreads and standard deviations up around 78 or 79 grains although you might see slightly better precision (group size) at the low end, around 73 grains.

Problem is I only have h1000 and n570
Have you tried n570?

While retumbo is my go to in 30 nosler I have used 1000 also just a little slower mode no big deal, I wouldnt hesitate to try 570 , if I had any I would most certainly try it. Broz over on long range only used it in his build so you should be able to get some good information there.
I loaded 10 rounds last night of n570 and 10 h1000 I'll shoot them side by side in my ladder test see what does better
Will do

Any results to report?
N570 had me about 150fps over h1000
