CD180 antigen is a protein that in humans is encoded by the CD180 gene.
CD180 is a cell surface molecule consisting of extracellular leucine-rich repeats (LRR) and a short cytoplasmic tail. It is also known by the archaic terms Bgp-95 and RP105, for the founding designations following discovery in humans (1988) and mice (1994), respectively. The extracellular LRR is associated with a molecule called MD-1 and form the cell surface receptor complex, CD180/MD-1. It belongs to the family of pathogen receptors, Toll-like receptors (TLR). CD180/MD-1, by working in concert with TLR4, controls B cell recognition and signaling of lipopolysaccharide (LPS), a membrane constituent of Gram-negative bacteria.

    200 gr or 180 gr bullet in a 300 Win Mag

    I'm leaning towards the Serria 220 gr RN bullet as a good all around Western Oregon hunting bullet. I see on the internet the Nosler Partion is highly thought of as well so my question is what's better the 200's at just under 3000 fps or the 180's at just over 3000 fps?
