I'm getting a Winchester 670(.30-06). Apparently it is an economical version of the Winchester Model 70. It uses some type of "push feed" method. Are the parts interchangeable with the M70? If not, where could I find them? What is the capacity? Are there any problems with firing mil surp .30 caliber through it? And where can I find a manual? Hehe... yep, I'm clueless about it alright. All I know is that Winchester is a good manufacturer and the rifle itself is very accurate. Thanks.
