RE: winchester X-150? good/bad?
I think they are made by CVA but that would not keep me from buying a rifle. You know what you bought and the load data for it and it will perform to the expectations. CVA guns I have owned are tanks and have been though heck and back. Are they as good as my T/C's? No but they cost a lot less.
Congrats I am sure you have bought a great rifle that will serve you well. Winchester does not put their name on pieces of crap.
