Velocity and accuracy

I find a good chronograph to be an essential reloading tool, saying this if I can get a marriage of accuracy and velocity great. In recent years I am transitioning all of my hunting rifles to hammer hunter monolithic bullets for several reasons lower maximum pressure because of reduced surface area on the bullet caused by a series of parabolic band ridges on the bullet. The side benefit of this is increased velocity which seems to mitigate a monolithic bullets reduced g7 BC. While I am no expert on Hammer Hunter monolithic bullets I find them to be substantially easier to find great accuracy compared to cup and core bullets design. By going with this bullet design, it is essential to know the actual barrel twist rate to achieve high bullet stability usually a person has to drop down 10-15% in bullet weight compared to a cup and core bullet design to achieve the desired bullet stability. thus preventing a bullet from key holding on target. My preference is a minimum of 1.7 but prefer a value closer to 2.0 or more. In my 280 Remington I am achieving 3170 fps with a 131 gr hammer bullets with a 5 shot ES of 6 with a sub MOA group. All of this with zero lead to potentially poisoning for birds that will scavenge a gut pile. Sad part is that it takes very little lead to cause lead poisoning to any raptor!
