I picked up another 8400 in 270 wsm with the idea of doing a 6.5 prc on it. I thought it'd work well due to the 3" mag box. I've had a 7 wsm 8400 for years that's one of my favorites.
I had a 300 wsm too but I gave it to a friend I hunt with after we both drew good elk tags a few years ago. He shot a 5x5 bull with it and like the gun . He always helps me out so I told him to keep it.
What would be a good contour to do a prc on a Montana but still be able to thread it for a can at 22"?
Does shooter71 have a website for gunsmithing?
