I have been hunting with my Rem 700 ML for the last 4 years and I've been really pleased with it. The load/bullet combo I've settled on is 80 grains of Pyrodex and the Knight Red Hot sabot. Its a deadly bullet because it breaks into four parts on impact and does an awesome amount of damage. One thing you will love about the 700 ML is when you have to hunt in the rain. Keep a roll of plastic wrap in your hunting gear and when it rains, all you have to do is put on your cap, close the bolt and wrap the whole receiver area with plastic wrap and you are good to go. I've hunting all day in pouring rain and the fire lit just fine when I got back to camp.
Good luck!
