6.5Grendel vs 5.56NATO as General Purpose AR15 Chambering

[stanc]

I can do the testing but you design the test with one caveat. It will have defined standards and if any of the cartridges fail any of the tests, it will be considered as FAILING that test.

That's very generous of you to offer your services. However, for the kind of testing I'm talking about, there is no pass or fail.

What I seek is comparative data showing relative performance, as in the example below comparing 5.56 barrier penetration.
