With all these 5 shot groups, and I am assuming a newer rifle.
Could the bore be getting fouled?
Have you scoped the bore?
Bought used. Supposedly less than 200 rounds.
I cleaned the bore good this week and it didn't seem to be excessively dirty. I changed mounts (talleys) and scopes (conquest) and shot a few groups this morning. Didn't have a lot of time, but it appears to be more of the same.
Shot groups of 3.5", 5", and 2" at 200 yards and shot just over 3/4" at 100.
