Tanner,

I too was surprised at some of their powders for 7RM. Not sure mine has seen anything but R22, And Magpro off the top of my head.

I just found it interesting that Nosler online had the 2 rounds so close even though the .280AI had 2" more barrel the 7RM had more powder.

I do know the 7RM will beat it with equal barrel length but again it can use more powder.

There is simply no replacement for displacement but the race isn't a run away for sure.
