what is the difference between 6.5 300wsm and the6.5 270 wsm in reamers

 

[L.Sherm]

Really nothing when it boils down to it, the 270wsm is a few thou longer at the neck shoulder junction.

Mine is a 6.5x300wsm but I use necked down 270wsm brass. The reason 270wsm is longer at neck shoulder junction is smaller neck.
