Thanks Wingbone.

Have another question. A couple of friends have Winchester 94s. One was made in 1964 and his other was made in 1966. Both of them have well-defined very sharp "thick" rifling in the barrels. The other friend has one made in 1970. It has a shiny bore but the rifling is not as "thick" and well defined. Did Winchester redesign
the barrels or do something differently after the 60's. Does sharper rifling affect accuracy?

Thanks for your patience and answers,
