Greyhawk my friend , contact me anytime you like . But I must say in advance , I have no tricks . When I set up , or put together a 76 I try and set it up as close as I can to original spec's . that's it except that I fit the forearm wood a tad loose . I will say this the most accurate original 76 45/75 untouched rifle that I have , has a slight looseness to the forearm , shrinkage I expect , but she shoots a ragged hole group if you hold it . Without a doubt my favorite rifle . The best shooting 94 , 86 , and 73 that I have all have this in common ,a slight looseness in the forearm fit . Coincidence or is there something there ? DT
