You can pretty much use Sierra load data for similar weights in Berger. Just a couple things to remember. The Bergers especially the VLD's usually like to be jammed pretty tight in the lands for best accuracy. Another thing to consider is the Berger VLD's have a shorter bearing surface than the Sierra's so they will take a LITTLE more powder than the manual says, except that they want to be jammed and that negates the lessor bearing surface trade off. Hope that makes sense.
