I have been reseaching and on a few forums people are talking that the early Ruger M77s and #1s most with bull barrels and years up to 1973 or 74 were Douglas Barrels. Ater that they were Wilson. Also was said that if your rifle had a bull tube and a old style bolt handle that this might be the case. Anybody heard of this? I wish there was a wedsite that would tell you the year and modle according to the serial#.
