AR caliber suggestions
I am gonna build an upper but don't know what caliber.
I have a couple in .223 and a 6.8spc so not that.
I only hunt deer,hogs and vermin(yotes and bobcats).
I reload or handload so no limits except I don't want to fire form brass.
It must fit the .223 length magazine.
Question: What would you reccomend and why?
