I bought a new Henry Big Boy .44. to condense, i had an issue with it shooting 8 to 10 inches high at 50 yds no matter how i adjusted. Sent it back and they replaced the barrel cuz they said something was wrong with the rifling. now it shoots great BUT there's still an issue. After sighting it in i found that after each shot i would have to reposition the rear sight on the elevator because i guess the kick would move the sight all the way back. Anyone have a solution for this? thanks in advance. btw I love shooting this gun it is otherwise great!
