Converting 300 win to 308

Well I built a 300 win on a older long action Savage I had to get into long range shooting. But the place I was planning on shooting is now closed and my Closest range is only 100 yards. So I decided to Rebarrel to a long action 308. So what will I need? Barrel, bolt face, firing pin? I have the lug and barrel nut already which are from Sharp shooters supply. Also I know I will need the 308 go gauge. Im going to have to figure out how to make the 308 feed reliably out of my Acis 300 win magazine. Anyone done this yet?

you will need a barrel, bolthead, and 308 magazine. Plus the tools to swap the barrel out of course(go/no-go gauge, nut wrench, action wrench).

You are probably going to need a 308 mag as the win mag is bigger indiameter. I would try the old one first but if you have to change,I am sure you could swap or sell it easily.

Can I use the parts from my magnum bolt extractor and springs ect...Also im going to have to make a longer mag work because my Inletting is for a long action Magazine. I was reading that people have made the 300 mag work. Will I also need a firing pin?
