I need the C.O.A.L. for a .30, 230gr hybrid in a 300 Blackout.

. . . I know "less than magazine length" But I would like to at least know what Berger says it should be.


I am looking for a very specific velocity, and as you know COAL can be one heck of a variable in that endeavor. I would much rather not have to struggle with it.

TIA.
