Agree, and some sources list these two as the same, they are not.
LoveX Do63 is a tad hotter in my 16" AR and I get more fps from Do63 in both sub/super-sonics.
300 BLK is a fun little cartridge, more like a pistol load than a rifle load.
I'm playing with Hornady 160 gr FTX (30-30) pill with Lil`Gun and haven't found an accurate enough load yet...
