I'm a rookie to Savage rifles so I guess this could be considered a rookie question. I have 2 lefthand 300WM rifles. One the serial number is 128132 and the other is serial number F863356. The older one is not a shrouded bolt so I could rebarrel. What I want to do is rebarrel one to 338WM. Now I have found out the 338 is the parent case to the 300WM, the max sammi pressure is the same between the two from what I have found. The bolt should be useable between the two. Now my question is this feasibly a good build and I should use the newer rifle? The older one is a 110 and the newer one is a 111. Has anyone done such a build or is there some fact I am overlooking. I know the 300WM will take any game around but I am looking for a good bear gun. Any suggestions would be appreciated
