I have yet to use them during hunting. At the range, they are awsome! I am using 90 grs. of BH 209 and getting great results. I have my Knight Vision set up for the long shots and have not used it in the woods. All my hunting so far, the last two years, have been in the thick stuff.
I have only one complaint on the bullet and that is they are a b***h to load. Other then that, I would recommend them to anyone.
