I only have experience with my 6.5CM with deer using the 143 ELDX and have seen more and more postings about guys moving down to bullet weights for the 6.5CM in the 120's. I know that will pick up some speed but wondered about energy at extended ranges on game.
My plans are for an antelope hunt in Montana next year where the ranges in this area are 500+.
I have used the bullet weights in the 120s for my Grendel and that seems to be working out ok so far.
Your thoughts on lighter bullets
