If you decide to do the 209 kit,don't do the the normal 209 kit that still uses the factory "slam fire" firing pin.Get ahold of Luke @ arrowhead sporting goods in Iowa --
http://www.smokelessmz.com/ Luke can convert your factory slam fire assembly over to a regular style firing pin that uses the 209 primers.This is the best kit available for the 700ML.You won't have to worry about all the blowback from the primer and powder all over your face and your scope if your using one.Hope this helps.............Rich
