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

. . . I know "less than magazine length" :rolleyes: 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.:rambo:

Rumbler - 300 Blackout is not listed in the Berger reloading manual.

Try looking at this and see if it gives you any useful information... it lists the 230gr THOTM (Tactical Hybrid Open Tip Match) COAL to be 2.245".

Thanks, Gentlemen.

I will be happy when there is wide enough use of this cartridge to flesh out the open source data repository. I am certainly going to log all the data I can generate, both high and low.
