Yeah they are a good ML'er.
The Aerolites use a copper coating and then the other "graphite" looking coating you see on the outside of the bullet.
I havent been to impressed with the bullets performance when shooting into sand and wet news paper but before i make a final decision, i put in for a new mexico deer tag to see if i could test one of these bullets out on a big boy down there.
First testing on video:
