300Blackout Journey Load Data

300Blackout Load Data — Heed the warning below

Again this data is not intended to replace the appropriate reloading manuals data and should not be used without verifying and double checking the loads between two different official published reference points — IE reloading manuals. If you elect to utilize any of this data it is at your own risk. These loads did work fine in the rifles indicated below. As I get to spend more time on the range with 300Blackout I will be adding to the data below and taking pictures of the groups.

Though fired successfully in my rifles any reloading data represented in RED LETTERING represent a known load to exhibit pressure signs — Flat primers, blown primers, case splits etc.
