Is there any printed load data for the 300 black out. I am lookinf for info for lil gun powder and 147 grain bullets. allso the 110 grain.
thanks in advance
Lee dies in 300 blk come with data.
Hornady 9th edition
Hodgon's website
Just a note since I only got back from shooting my first handloaded .300 BLK ammo. I'll post a more detailed report once I have all the data analyzed but I used:
Cut down and resized 5.56 NATO cases.
Sierra 165 gr. Jacketed Spitzer bullets
Hodgdon H110 Power
CCI Magnum Small Rifle Primers.
I didn't find an exact match for .300 BLK and 165 gr. but used a table that showed 168 gr. at 13.7 gr of H110 giving ~1650 fps.
I loaded up 25 rounds of 5 each with 12.9 gr, 13.1 gr, 13.3 gr, 13.5 gr, and 13.7 gr.
The 12.9 and 13.1 cycled by 16" CMMG AR rifle just fine but the chrony showed pretty large variation in speed. At 13.3 things started to settle down and at 13.7 I was getting very consistent velocity. I wasn't really aiming for a tight group but the rounds were pretty much right on target.
This was my first try at reloading .300 BLK and the first time converting one case (5.56/.223) to another. Overall, it turned out to be a lot easier than expected.
