351 Winchester, from what I understand the current Corbon offering with the 110gr JHP is still pretty darn warm. Some folks claimed to have gotten over 1100fps from 4" barrels. On corbon's web site they state that this load was tested in a 1.875" barrel for 1050fps. Speaking of the Hornady 110gr +P Critical Defense has anyone actully run this one over a chronograph from a 4" barrel? I wonder how close this load is to Hornady's claims?
