Thought Id share... So I have a MSR10 Longrange chambered in 6.5 Creedmoor. I have mounted the Viper PST Gen II 5-25x50 EBR-2C. So far I’m a happy camper but, I mounted the scope with medium rings, they are too low and I need to raise it a bit to get a good cheek weld. I got it hitting paper at 100yards with some factory ammo but, nothing to rave about. This was part of the break in but, I hand loaded 50 rounds in FC brass, 42 gns of RL17 and topped with the Sierra 130 TMK and continued the break in. Below is the last 5 round shot group. Temp was about 16 degrees.
