sight in issues
Hello, I have a question regarding an initial sight in for a new scope on a Browning A-Bolt Stainless Stalker 7mm Rem Mag. I am going to assume something may be loose possibly? I did have the trigger turned down to 3.5 lbs as well. My first group at 100 yds was within 1 inch, no problem. 2nd group was just over an inch. 3rd and 4th groups opened up to 3 inches plus. I went home, cleaned the barrel etc and went back to the range. My groups still were in the 2-3 inch range. My rifle has always shot good and now its erratic. Any advice? Thanks!
