ooks good. When you consider the fact that you are using 150 Factory Ammo & also the barrel will get better with more rounds it is quite good. Most likely the 165-168gr. range will do better yet. If you are a reloader get some good quality brass, Varget & fed match primers with 168MK , Bergers or even NBT to see how it will group, I believe you will be happy as it appears your rifle will be a shooter.
BTW, I like your scope, good choice.
