I already loaded .223 and .308 so the 300 was an easy choice.
That's just it I don't reload, I want to start, I'm just not a big fan of the 300 yet myself I'm not gonna use any suppressors which is where 300 really seems to stand out most aside from its compatibility with 5.56 cases, mags, and bolt.
This upper is gonna be used for greater distances mostly because I will have my 5.56 upper to swap them around when necessary.
but 6.8 close range (50-100yds) will do much better then 5.56 damage wise.
