I am beginning to load for 6.5 CM. My Hornady bullet comparator kit does not have an insert for 6.5 bullets. They have a #4 - .25 & #6 - .27. The kit indicates that there are six inserts which I have but there was no #5 which I'm guessing would be for the 6.5. I used the #4 - .25 and guess that its OK because bullet seating is a relative measure. Once I figure out where the bullet touches the lands w/ the #4 insert and keep the same setup for determining seating depth for the right jump I'll be OK. Just odd that the 6.5 is not part of the basic kit.
