300BLK Capabilities w/ Handloads
A lot of people argue over the accuracy capabilities of the 300 AAC Blackout. I hope this proves them wrong.
I did this over the weekend with my handloads that have been in development for ~6 months. I was about ready to give up and move on to something else, but my 16" DD S2W barrel really impressed me this weekend.
Primarily Noveske w/ a 16" DD S2W 1:8, Geissele SSA-E
125gr SMK
18.2gr H110
CCI400
FC 223, small headstamp reformed brass. I've heard the large headstamp has been problematic
2.200"
No velocity data yet
No issues at all, has properly fired and ejected everything put through it thus far. All supersonic from 110gr - 150gr bullets & H110.
5 shots @ 100yds. = .440". Very slight pressure signs.

The problem you have now Onyx, it is almost impossible to improve on that group. Good shooting!

Dam nice group! With H110 too! My powder of choice is Lil'Gun as H110 seems to beat up brass in a couple of loads. FC.223 brass is what I used the most since it really short most of the time for OAL. I've gotten 5 or so reloads with suppers with them then the pockets are usually shot! H110 likes to be compressed for the best burn but is very unforgiving an prone to pressure spikes with over compression.
