6,5 Grendel a barrel burner? No

[mlmiller1]

That is a very interesting "quick read" article. I wonder if the conclusions are valid? I suspect the 6.5 grendel is not a barrel burner but I suspect that due to the fact velocities are quite a bit lower & powder charges quite a bit less than say a .260. If this graph has any validity, it could be very useful to anyone considering or comparing a particular caliber or calibers.

Thanks for posting that link!
