Trying to determine barrel twist for two different barrels. Both from M77R's....one made 1970....one in 1978. After numerous runs with all the rods I have access to, I'm coming up with a 1 in 11" twist for both.
My reading/research to this point leaves me a bit skeptical. I anyone has a similar vintage barrel/s, any confirmation that my results are accurate would be most appreciated. Cal. is .243 for both barrels. (edit)
