I have a Winchester Model 70 CRF in 7rem mag. It has the old style trigger and the short magazine box. I was just going to rebarrel it with a faster twist and chamber it in 7 rem mag again until I realized how short the mag box is. 3.4". So, I started thinking about what else I could chamber it in and have a few questions. My first question is, how do you think a WSM cartridge would feed using my current box and follower? I know that it may limit the number of cartridges I can have in the box, which is not a big deal to me. As long as I have one follow up shot. Second, what cartridge would you go with in this situation? I already have a 7mm/.284 barrel, but also don't have a problem buying a different barrel. This rifle will be mainly used for deer and antelope, but on occasion it may go with me for elk. Last question: Other than the Wyatts mag box, what are people using with the Win 70 to get a magazine with room for some longer bullets? Thank you in advance for any input.
