I loaded some Berry's 220gr in 300 blackout. I didn't take my chrono so not sure the fps but they ran well, but didn't alway lock back on an empty mag. I'll load some more and take them to the outdoor range and see what they are running and how much more I can go or if i need to change powder. I don't recall what I used on these, probably 1680. I have some CFE BLK and I think I did some with something else.
just checked. 220smk 11gr 1680, 220smk 12gr CFE BLK and 220 Berry's with 11.1gr 1680 (I was too lazy to set the thrower to 11gr).I know we really shouldn't trust other peoples' recipes as reliable, but I was getting just a shade over 1000fps from a 16in barrel using 10.0gr of CFE Blk and a Berrys 220gr, with some case capacity left.
The same ammo used in a 12.5in 300BLK AR did give me reliable bolt lock-back, but I think that's as much a function of the buffer tube as the powder load.
