Re: Building a new rifle?
Thanks for what? I must be missing something.
Figure out what you're gonna do with it (targets or hunting?), what distance do you want it to perform that task out to, select an appropriate chambering, go purchase a Savchesterington chambered for that cartridge along with capable optics, and then shoot the shit out of it at those distances.
If you aren't sure about any of these things, read up on the subjects that are fuzzy for you in books (no, they're not obsolete), magazines, and articles published all over the internet by reputable sources.
Then, maybe, other people will know how to help you.
