Doe anybody know what the twist on a 1978 M77 in 7mm Rem Mag would be?

call up the ruger records dept, provided it is the original barrel and you have the serial number, they will have the correct info...

The 1974 answer is 1 in 9.5"

I know the M77 Mark II is also a 1:9.5. So that may be the answer in this case as well!
