Need info on 6.5x270 WSM

[hoghunter]

built a 6.5x270 WSM on an old 721 30-06 action. Having feeding problem from magazine. Anyone know specs on 270 or 300 WSM action[rail spacing] Looks like I need to mill small amount of metal off rails but do not know how much.

just take a small file and file a little at a time from both sides
of feed lips you can do it it's not a hard chore.
