7mm SAUM 180 Hybrid Load......Build it like I say and it will shoot with this load!!!

So I spent the weekend with N565 & my 7saum. After numerous firings my rifle found only 1 node & it was at 63.5gr which happens to be same exact charge of H1000 it likes. I worked all the way up to 65.5gr & never got a heavy bolt, but groups were 1.5in…..
 
Was able to gather data off the Magnetospeed on both powders & this is what I came up with on my rifle

Best groups with N565. 3 shot & 5 shot. Second pic I choked on the 5th shot. 🤬

That's about what I figured at those charges. Did you pressure out or why did you quite going forward? I'm guessing you couldn't reach the 2940 node
I was getting ejector marks & definitely noticing recoil increases….shooting suppresed at 65.5 that load is hot AF….! My rifle was obviously showing me it didn't like the red zone. I was getting velocity reads in 2.9k zone but not the groups
