Over the years I have had several rifles built on Rem 700 and custom actions. Now I want to build one on a Winchester Model 70 action. I have always been a fan of them, mainly because of the nostalgia. I have a mid 70's Model 70 7rem mag that I have shot a lot of animals with over the years. Currently I have the opportunity to buy an almost new Model 70 SA Sporter CRF in .325wsm, for a very good price. My idea is to build something off of this action. I am not sure exactly what yet, but to get to my questions; Does anyone know what the magazine length of these are? I have heard that they are around 3.025, but was hoping to get some confirmation. This will help with my cartridge decision. Also, anybody build off these actions before? I am having difficulty finding stock options. McMillan is an options, but looking to see if there are others that I am missing. I have searched the internet with very little success. Thanks for any help you guys can provide.
