Get the magnum cases for this cartridge
answered 2 years, 3 months ago
300wsm was too big in the magnum size and .348 win has a larger case.
what i did was i soaked the loops in hot water and stretched them by adding one size larger round bar every time. eventually it made the loops larger. i would suggest that you do this, it is a nice case and it's not hard to do.
