Has any one chronographed the IMI SS-109 ammunition?  If so, what is the velocity, if you don't mind sharing?  Also has anyone found a load that duplicates the IMI SS-109 round?  Thank you in advance.  Sgt. Mike

  Thanks for the thorough information.  I have alot of boxed IMI M855, but use it rarely.  Saving it for whatever may come along.
