Work between 56 and 56.5 for tightest group and go.

Your barrel is showing a nice node there. Many barrels don't flatten out quite so nice. Shows a forgiving barrel.

Thanks for the reply, will work in that group and shoot a bit further. PS: first time using the powder, so my POA was really off Was using 57gr of R19, its amazing how different the trajectory are.

It is quite amazing to see how changing powder affects the harmonics of a barrel. It does look like your barrel likes the IMR4350 showing a nice clear node.
