6.5 Grendel – 12in – HRN 123gr SST – Hodgdon BLC(2)

Remarks:

Due to the current component shortages, I was using a powder that was known to be less than ideal for this application and resulted in less than 100% burn rate.
To add insult to injury, in a rush to get this done, I tested this load before I finished my shooting bench so testing was done from a fold out table and chair. Needless to say this wasn’t my best shooting day.
Even considering that the groups could have been better, this is not a load I would recommend.
