My first m77 guide gun in 375 Ruger had crazy high velocity, but I spent a few days trying to figure out why the best group I could get at 200 yards was 20+ inches.....
after sending the rifle back to Ruger and checking up on it they told me that they found loose stock screws and after the tech shot it the next morning they would most likely be sending it back to me ( yes I checked those already), the next morning they called me and told me they were sending me a new rifle, when asked what was wrong with the one I sent in they said they had no idea lol..
But with a little load development the new rifle shoots great, makes a great elk rifle with no brake on it. 260 gr accubonds @2950 from a 20inch tube
