bore sighted a 7.7 jap at the neighbors mailbox, about 200 yards away. shot the rifle at about 30 yards and it was way low. kept cranking the scope up and shooting and when it got in the general area there was about 5 feet of difference between the bore sight and the actual adjustments. the end of the barrel has been sawed off, looks fairly straight. if it is crowned at all, it is slight. could the crown deflect a bullet that much or is the barrel bent? I'm probably going to cut it to 19 inches and attempt to crown it. anybody ever seen this problem?
