I'm handloading for my AR-15 and have Alliant Reloader 10x powder, Speer 50 gr SP bullets, CCI 450(magnum) primers and cannot find any load data that covers what I can get my hands on these days. Most of what I can find during my research is to take the min load and back off 10% to compensate for the magnum primer however i've also heard that 10x burns a little hotter faster so can raise the pressuress.. My AR IS rated for 5.56 NATO. Any help with starting loads would be greatly appriciated!!
