.280 Enfield...Ahead of its time

[JASmith]

I think the 6.5x45 looks pretty interesting.

This gives us at least three cartridges that should be looked at more closely for the LMG/MMG role:

1. The 6.5 Grendel with extended COAL
   
2. A 6.5 based on the SPC but with an extended COAL
   
3. The 6.5x45
   

Each of these have interesting characteristics and each may be good enough.
