I built a 300 blackout earlier this year. Not having much luck with factory ammo. I want to shoot a good subsonic load maybe in the 208gr A-Max and I would also like to shoot something in the 110 grain range. Wondered if I could hear from those that have experience in loading for this cartridge. What powders, primers, etc as well as what accuracy your getting. Mine is shooting about 3 MOA right now with the 210 Remington and the 110 Nosler factory. I don't expect a sub MOA from what I have been reading but it has to be better than this.
