According to Nosler load data using 160gn accubonds with a max load of 61.0gn of N165 powder I should have a velocity of 2904. Using two different chronographs my max average speed with that load is 2660 on two separate occasions. Sierra bullets load data for their 160gn sbt has a max load of 67.4 of N165. Starting at 65.7 and working up to the max load I'm getting chronograph readings in the low to mid 2900"s. Is something wrong with your data?
7mm Rem Mag load data error?

In my opinion Nosler’s load data is always quite generous with their velocities. Try to load to their stated velocity with a chronograph, watching closely for signs of excess pressure.

So many variables...barrel quality/length, brass, etc...I have had really good success in several 7RM shooting 160 grain bullets using H1000...much better velocity nodes.
