What are your favorite 300 Blackout loads? Wanting to set up my AR for 300 B.O. Looking for input.
Thanks,

Develop loads that work the best in YOUR rifle.
The barrel will tell you what it likes and what it doesn't.
Hodgdon Reloading Data Center, on-line, can't be beat.
5.0 grains of Trail Boss.
Hand cast (40:1) 147 grain hollow point.
CCI primer.
990 fps of explosive subsonic fun out of a 16.25" barrel.
I have not found any reload data for trail boss and subs out of the blackout. I did a bunch of research on blackout sub loads and came across trail boss in a few post and decided to try it out. It's incredibly consistent and my extreme spreads are less than %2. I had a mold modified to fit my requirements and can easily print moa groups at 100 if I do my part.This is the info I had been looking for. I have had good luck with 308 150gr soft point and 10gr trailboss in my bolt 308win gun running subsonic.
Its really interesting your getting close to what I got on 308 with same projectile and half the powder. just goes to show how its not just the powder amount but other things.
Any reloader manuals have a 300blk & trailboss documented?
No favorite load yet but finding the Barnes TAC-TX 110 gr very popular for supers, just ordered some @ $29 per 50 shipped, Powder Valley. OOS most places @ $33 +
