Anyone have the latest Hornady loading manual and willing to share some info?
If you're familiar with the 300BLK round, there's a lot of conflicting info out there. I'm trying to work out a load for my new 300BLK upper build with Hornady 125gr SST.
Hodgdon site says 16.7 - 17.8 of H110
Sierra manual says 17.1 - 18.3
I'd like to know what Hornady says for the 125gr SST and H110.
Thanks for any help you can share.
9th edition 300 whisper/AAC black out
125 and 130g bullets...H110 start 14.6g 1700fps....max 18.8g 2100fps
16" barrel....7.5 twist
Hornady case
Winchester small riffle primer
Thanks so much! Those figures are way different than others, all from 16" barrels.
Hodgdon says 17.8 max = 2118 fps
Sierra says 18.3 = 2200 fps
Hornady says 18.8 = 2100fps
I'm going up to 18.0 and play it from there for accuracy & function. Thanks again!
no problem.
