Berger 6mm 80gr varmint FB

[bikehe]

Anyone using these 80gr varmint and how do they perform on your coyotes out to 500yards. I recently found a load using the berger 87gr vld hunting that shoots better than .5 at 200 yards but when I went to get some goat for the freezer these pills were drilling holes straight through. I really like the bergers for accuracy even though I've never tried anything else but are the jackets on the 80 gr FB thinner?, as I need a bullet that will expand better. Mostly shooting dogs, foxes and goats out to a max of 500yards, or will I be better trying something else. I read a lot about the 75gr v-max. I do have some sierra 75gr to try as well. Rifle is a 1-10 twist. Thanks for any info you guys may have.
